"Obsidian has created a RPG and a Fallout game and not a sandbox game like Bethesda's Fallout."
Don't get me wrong, I loved Fallout 3 and I like sandbox games, but the Fallout series wasn't really about exploring the world until Bethesda picked it up. Obsidian has focused on the qualities that make a Fallout game a Fallout game and not a Bethesda game.
I think that's a fair thing to say. Bethesda games include quests as a means to drag the player through the game world. Obsidian and Bioware use game worlds as a stage on which the players can act out the quests. Those who prefer Bethesda's approach will always feel slightly frustrated by games like those by Obsidian and Bioware because there's a slightly artificial feeling to the world, as though it's a
set rather than a
place. To those who prefer the other style, any game where they build the place first and then decide how to entertain the player there might naturally prove frustrating since the game-world, rather than quest design, was always foremost in the developers' minds.
There's no reason why both companies can't do both well, and to a large extent they do, and to a greater extent,
all the leading RPG companies are improving in all areas. For example, I thought Fallout 3 had the strongest quest-writing yet in a Bethesda game, and Mass Effect 2 was certainly an exponential improvement on any previous Bioware game when it came to world-building. I'm just not sure that we're ever going to see a
perfect game that does everything equally well in every way.
If we're in a position where one type of player enjoys Fallout 3 but prefers New Vegas, and another type of player enjoys New Vegas but prefers Fallout 3, I think that speaks volumes about the quality of both games, and makes us very happy players.
