I'd rather have a full blown expansion, but that seems unlikely.
I understand where your coming from with expansions,but expansions ( to me ) are DLC only bigger. I don't mind a few DLC's. If you buy a few DLC's it's basically an expansion anyway,just has different areas etc. Another benefit to DLC is we'll get more than one. Say they did one big expansion,and some people weren't to keen,then they only have the expansion. But different DLC might appeal to more people, because they can chose which they like...hope that makes sense. The DLC's for fallout 3 were ok in size i thought,and there was 5 overall ...i think.
Don't get me wrong,bloodmoon,tribunal,and the shivering isles were exellent,so i do see where your coming from. But either way,i'll probably buy them. There is benefits to both. DLC can have more benefits,as in choice,rather than one expansion. If someone doesn't like the sound of the expansion,they ain't going to buy it. So say, they did 5-6 DLC's that increases the chances of someone buying something,because they have more of a choice. I'm one of those people who is happy either way
