There's really no rule for what form you have to have the game in to add it to your list. Do what you want. =P
By the way, people would probably understand better that you're making a question if you change the sentence structure a bit.
"I can add games." - a statement
"Can I add games?" - a question
"I can add games?" - you can say this in real life, but in text we can't understand what you mean from the tone of your voice, so there might be confusion
