1. A decent Crash Bandicoot game would be so awesome in HD (like the old style with the portals and everything)
2. There was this fighting game I use to love on my PS1 but I forgot what it was called, all I can remember is you could choose you character and play co-op and you would go through and just fight all these people, you used to use a missile launcher to blow down this gate, and the you could smash the coke machine and drink the coke for life
3. There was this other driving game on PS1 where you go around in this car and do driving missions and it was a free roaming and your car could have missiles and guns attached. I think it was called self destruct
Thats about all I can remember from the good ol PS1 days
