i also checked out EndWar for DS - its like Dai Senryaku + Advance Wars? i guess the PSP version is the same way. dont have a PSP to try. nice pixel graphics yummy.
Theresia is pretty nice. Shadowgate but there are traps everywhere and you have a life meter. I pulled out a chair and for some reason a needle pricked me and i got hurt. so i go to the next room and try to open a door and i get like 10,000 volts through my body. it's ok though, i drink an elixer and i'm ok again!
