I've played a bit of 2 and a lot of 3 (and unfortunately, 4), but this was my first time touching 1. Some parts aged a lot better than others. The story is engaging and the way bits are sprinkled out through books is cool, the atmosphere and music combine in a great way to be just eerie enough to keep you on edge, and the overall spookier, more horrorish vibe than the later games sets a nice tone for the game. I'm very mixed on the gameplay, the actual mechanics of it were no issue to get used to and loot and skills were pretty self-explanatory.

The more glaring issues come from the grid-based system. When levels start getting crowded, moving around and aiming gets really rough, with it feeling like you're fighting the game just to hit your target sometimes. I had a good bit of fun with it up until Hell, and Hell didn't make me hate it entirely, but I'm not particularly in a rush to return.
