FTL. Very fun roguelike game. Cheap on Steam. It's hard to describe, but you should look into it.

I already have this game on steam, but thankies is really fun XD

You could play...X-Wing. But that have came out on the 90s, I think. Why is that the only other space ship game I can think of?

I like games in more free gameplay style traveling in space, choosing destination and taking missions.. and trading like Freelancer, X3 Game Series, Vega Strike and so ^^

Or something action game sci fi themed like Dead Space, Mass Effect and others

EVE online?

I see this game, but seems need pay all months like some MMORPG games. (And MMORPG games drop realism and logic sometimes)

Thank you very much, I will check here ^^

Secconded, but I had to add a few comments about it:

- Warframe is a multiplayer, always-growing indie action-shooter. It's pretty good, has a lot of action and a very interesting scenario, but part of it is still a bit grind-based. The game evolves a lot in each few months, though, so that can be fixed eventually.

- Dead Space is an EXCELLENT concept, but it gets totally lost torwards the third game, and is now just an action-shooter cash-cow. Still interesting enough for the scenario and mechanical design, though.

- Mass Effect is a masterpiece, but you need to grab some of the DLCs for a "complete experience" (and that includes the mandatory Extended Ending DLC; 'cause the original ending sucked).

- Crysis.... is nice for the mechanical design, but it's also the most confusing and undecided sci-fi series I've ever seen. It starts with high-tech military fiction, goes trough alien invasion, alien mass infection, urban cataclysm, meta-human sci-fi, dystopian future and post-apocalypse; and that thoughout 3 games. If you want to go for the story, forget it. But it's worth it for some nice design and scenario ideas.


And if you like multiplayer FPSs, Blacklight: Retribution has some AMAZING scenario and content design (specially mechanical).

I think the Extended cut of Mass Effect 3 is free DLC.

It is, thankfully.

But there are some paid DLC that are basically mandatory, if you want a "complete experience" (like both character-adding DLCs, and the Arrival DLC, for ME2; and The Citadel and also the Prothean DLC for ME3).

...And that's a bit sad, because some of those DLC's content is crucial for the plot, and yet you have to pay extra for them.

What is the Mass Effect game style? I see some videos of this game, but I'm not sure how the game really is. its more open world like GTA or Ender Scrolls or follow a fixed storyline? I like more open world games choosing the quests and exploring the world.

It depends on the game, actually.

ME1 is a bit more traditional; combat is less action-shootery, more RPG stats thingy, classes and weapons are more stats-oriented, and you have a pretty much fixed storyline, although you can choose which location you're going (some locations will belong to the main plot, some will have sidequests, some are explorable areas). A few stuff can be made out of order, but not much (usually sidequests, or clearly parallel objectives).

In a sense, it's more Final-Fantasy-esque (specially "post-acquiring-an-airship/chocobo"). It's not exactly "open world" like GTA or Skyrim, it does have a fixed storyline, but you have some freedom of exploration (for example, you can travel to a hub world to buy equipment or get sidequests, or travel to a distant world to complete a secret quest, instead of directly going to the "CONTINUE STORYLINE HERE" worlds).

ME2 is more action-oriented, with a cover-based action-shooter combat (some RPG combat elements either vanish or are simplified; such as the weapon upgrading system, or the character stats). You have some storyline branching (a bit of it will depend on ME1 decisions and on acquired DLCs), and some storyline parts can even be made out of order (and sometimes the order matters in the end), but it'll mostly work as ME1 (Final-Fantasy-esque, with some degree of exploration, but a central storyline).

ME3 is like ME2, but brings back some elements (weapon upgrading system) and has more storyline branching (influenced by ME1 and ME2 decisions). The ending (specially with the Extended Cut DLC) will be influenced by decisions in all three games.

And all the three of them will feature RPG dialog more akin to Star Wars: Knights of the Old Republic (which was also made by BioWare, btw). And in all of them you'll have a faster-than-light-travel-enabled starship, so even though there's a fixed storyline (with some branching / non-fixed-order stuff and sidequests), that gives you a sense of freedom (akin to having an Airship in Final Fantasy).

thank you for the informations ^^

Thank you very much, I will check the games. I already have the X3 series ^^

Starwars: Knights of the Old Republic and Borderlands series. If you have a PS2 emulator then I'd recomend any of the Ratchet and Clank games

I love borderlands series, I'm playing Borderlands 2 this days ^^

There is EVE online, but you would need a good computer for it.

I have a good computer, but EVE need pay all months I wish pay one game only one time. And I'm not much into MMO ^^

Well, I can tell you what pc titles I enjoyed that I guess fall under "Sci-fi" games.

Alien Rage (like CoD in space)
Dead Space 1,2, & 3
Crysis 3
Doom 3*
Mass Effect Trilogy*
Warframe (free to play)
XCOM: Enemy Unknown (turn based strategy like game)
System Shock* & System Shock 2*
Deus Ex: Human Revolution*
Star Trek Online (MMO)
Star Wars: The Old Republic (MMO)

Thank you I will check this games, and I played some of this games ^^

Deus Ex: Human Revolution, seconded!

And wow, FC3 Blood Dragon... pure 80's junk-movie goodness!

Waking Mars, it's a game where you're exploring the underground of Mars and growing plants and it's pretty sweet.

Also, Rochard. You're a miner who has a gravity-gun type weapon that can also change all gravity around you.

I like myself a space/flight sim myself (I like the StarFox series, and a few StarWars sim games, among others), but the most current one that catches my eye is Squadron 42: Star Citizen. I don't think its out yet, but it looks AWESOME!

No problem ^^
