From what we've seen so far I'll have to agree there. It has a little less freedom, there is less emphasis on being just whatever the hell you want, from a junky to a porn start or a drunk or whatever comes to your mind... But still I feel that is alright. Still, this is alpha, there is a lot of space for more and more to the point. This game after launch has one possibillity that fallout 2 didn't had. Expansion packs!
On a side note did you know fallout 2 didn't even had half of the planned content? the team was hard pressed to finish the product so they had to cut a lot of stuff. That's kinda why stuff like, the guys searching for the holy hand grenade are nothing but just a funny scene. they never got to fully implement the quest lol.
