With graphic, town and race modding especially I love this game, it is really massive and has hours of playtime, though I wish it had more dialouge choices and effects and outcomes like New Vegas had. One thing I liked more about it than Vegas though was the guards and how I could build a bounty and join an assassin's guild. In Vegas, if I killed or stole from from someone then I'd just get shot at, not arrested
though obviously there's no point in being arrested in the wasteland, no jail until you get to California.
Bethesda really stole my heart with their games, though I wish they'd pay more attention to their modders and update their games a bit to be well...more realistic and pretty. The modders are better at their jobs than some of the actual game developers.
*points to sig* I'm counting down till Skyrim! But I doubt I'll be able to buy it right when it comes out
