games I've seen that do well on streams:
Binding of Isaac
Rogue Legacy
FTL
Crypt of the Necrodancer
Enter the Gungeon
Megaman series and Megaman X series
Mario Games

Wish I could do most of those but I'm only able to stream via PS4 ATM.

I've seen some streamers play some single player campaigns and story modes, but I have also seen some streamers play competitive titles for fun as well, so in all honesty what kind of games you wish to play I would be interested in seeing x3 Maybe further down the line you can also play games with your audience
