I like all video games.
Here are my favorite games:
Castle Crashers
BattleBlock Theater
Geometry Dash
Portal
Portal 2
PlazmaBurst
PlazmaBurst2
Happy Wheels
Divine Intervention
7 Days to Die
Pit People

I am working on becoming more of a gamer that I already am by trying out people's games and either giving it a star and a heart or criticizing it and telling the person that his project sucks.

:P
