There is a very useful toy Durango wild lands. This is an RPG with elements of survival in the world of dinosaurs. It looks like an arc, but this is a completely independent project with a skill leveling system and interesting craft.
Here are some good games. Sorted by genre. Stealth: Republique. Quest: Machinarium, Brothers a tale of two sons. Top-Down Shooter: Space Marshals. First-person shooter: Modern Combat, Deus Ex The Fall, Borderlands 2. Platformer: Valiant Hearts. Survival: This war of mine. Slasher: Implosion. Card: Hearthstone. Diabloid: Titan Quest. Visual Novels: Everlasting summer, Katawa Shoujo. Kinzo: The walking dead. Action: GTA ports, Bully. In general, you can download emulators NES, SNES, Sega mega drive, PS one, DOS, PSP, GBA and get a huge library of games from these platforms.
As a true nerd, I can say that there are no excessively suitable ones. There are a couple, but no more.
My favorites are leaving: Knights of the old Republic, Lego series, Reings, Stormbound: Kingdom Wars, Wayward Souls, Real Racing 3, Plague Inc. I haven't noticed any more cool games, maybe there are some.
