STO

I never hide anything, but I generally don't bring up Mario or JRPG's to my dude/bro friends who are more into COD, NHL and GTA. Not so much because I'm embarrassed, but because they just don't understand. I do have a little Mario on my entertainment stand, however.

pokemon games

there's nothing wrong with playing pokemon, loads of people play it.

if your 16-18 in school theres a good chance you hide the fact you play Pokemon. While in school I actually knew a fair few popular kids (coz I was the unpopular kid that somehow hung out with them) that secretly played Pokemon but they were all embaressed by it. 

18 here. Half the boys in my form have played Pokemon X/Y during free periods.

I came here to post this.

If someone comes over and sees me playing it, I don't mind, but it's not something that I'll put in and start playing when friends are over. 

I hide my Soul Calibur games when my family gathers at my house for the holidays. I leave Mortal Kombat out, strangely enough, which is what my nephews want to play. I guess the blood legitimizes the boobs somehow.

I don't mention RPGs. When a guy at work started talking to me about games I didn't bring up RPGs until he said, "and Final Fantasy VII is my favorite game ever."

JRPGs. Like Tales of, and other really niche games.
