Is Sands of time the first 3D PoP? If it is then I might as well say that I loved the game just for the puzzles, combat was meh not that good. About quick saving, lol, if it's a PC game then it usual has automatic savepoints, so I don't see why you have to lose 3h:25m of play-time, unless PoPSoT didn't have automatic save points but I beg to differ on that.
Oh wait, this is in the GC forum, ummm..I still think the console version might have automatic savepoints, if that's the case you don't need to replay 3h:25m.
If I'm wrong, don't shoot me.
