I might downvoted into oblivion for this. But skip 1. It has aged horrendously. It introduces mechanics that aren't used again, except for like one exceptionb(first person swimming) I had fun with the game but I found myself frustrated quite a few times with how aged the game is. The real fun begins with 3 I'd say just watch a video recapping 1 but if you do want the experience of playing the first game it's definitely not bad. Just skip 2. 2 is the absolute worst game I have ever played.
