Nintendo games, man. Super Smash Bros Brawl just dropped a bit from $50 this year.
MSRP for Animal Crossing Wild World is still ~$35 iirc --- I hate listening to dreams. It's like flipping through a stack of pictures. If I'm not in any of them, and nobody's having sex, I just...don't care
HD collections tend to stay quite pricey. Rockstar games as well.
And also some of the more popular Xbox 1 games. I was in a shop yesterday and saw Marvel Vs Capcom 2 for Xbox for £20 which is insane given that it doesn't really run on 360 and the XBLA version is £8 or so (I think).
Stranger still, Marvel Rise of the Imperfects was still £10. That game didn't even get good reviews.
Depends if they're still good. Skyrim is still $40 in my area after 1 and 1/2 years out. Games that were flops are like $20 or less now after less than a year. --- Stress: Not strangling the life out of someone when they desperately need it.
