I never gave this thought tbh, but it reminds me of a conversation in one of the Fire Emblem games where one of the archers says he's like archer number 3. So I'll go with that. #3.
Favorite letter? Cause I don't know, we were asking favorite number and it feels rude to leave the alphabet out of it.
Not at the moment. The newest game I believe I tried out was the Call of Duty: Modern Warfare II remake, which I played two online matches of and never touched it again as my friends stopped playing online in general. Since then, I've only revisited games I previously played.
