Lol i have to agree that they did sacrifice ai capabilities because they were terrible at driving... terrible.... And i didnt think about how its not just 360... hmm im sure that they will find a way and that battle sizes will have increased drastically... Because lets all be honest here, the battle at bruma was pitiful to say the least...
Fallout 3, alone, demonstrated larger battle capabilities (slightly). I'm sure they'll be able to get battles a bit larger, as they managed to do so with Fallout 3, but I'm pretty confident we're not at the point of actual battles, yet, but rather just decent-sized skirmishes. I'm sure they'll be larger than the Battle of Bruma, though, if they are in the game.
