I have the same problem for DDR, I have a few of the games but no pad to play with them. You did get the first Crash, Crash Bash, Spider Man( pretty good platformer), BustaMove, Pac Man World and the 3rd Syro in that set, which are all pretty good games as well as more desireable common titles since PS1 has been rising in price for the last few years or so.
Those are the ones I'm likely to keep, probably not Spider Man as I remember that one abit and don't really remember it being very good. I think it was Spiderman 2 the movie game where they actually got to be good. I'm probably gonna keep most of it except for Qbert, the two Star Wars games, and Pitfall. The rest should be generally fun. Jet Moto 2 I'm pretty sure I remember playing years ago.
Yeah, most of the other games in the set are pretty. However, the two star wars games are probably the only bad ones in the set, as Dark Forces is a FPS that looks pretty bad on the PS1, and the Masters of Tera Kasi plays pretty badly compared to the other 3D fighters from the day.
