Your definition of "great" and many others' definitions are divergent.
You're right about there not being much non-quest content, but considering how many quests there are, and how many options nearly all of those quests have, this isn't as much a problem as it would be otherwise.
Now, granted, I'd think there's a market for a dungeon pack which adds nothing but plausible dungeons and loots to make exploration more rewarding; the mod A World of Pain does this, and it has significantly improved my NV experience since sometimes I just want to rush in and machine gun something.
:ninja: many on this forum aren't bethesda fans, they're original fallout fans that like bashing bethesda, so i keep the groups seperated, bethesda fans like exploration and a plenty of enemies to fight, random events/encounters with lots of fantasy in their games, like 25 ft tall giants or giant robots..so the "many" people you are talking about, aren't bethesda fans, obsidian just isn't into open world games, their thing is more story, characters and dialogue and making a "plausible" or "believable" game world, i couldn't even care less about a game being plausible or believable, so i'm done with new vegas, it was an ok game, lets just let that stand for what it is, it deserves its 7.5 gamestop rating.
