Fun to Replay
It is really overwhelming to try to do everything first run, and sucks the fun right out of the game. I actually think this game is MORE fun the more you play it. I mean some of the "surprise" story element is gone, but seeing as it's an older game some of that is probably gone for you anyway lol. It's not a long game imho (especially when replaying), most of the achievements unlock without a thorough grind, so play for fun first and then see what you need to get. Totally replayable.
