Or they can make the second big city 20% smaller.
That too will work for me.
I've been wanting to give this game a pledge, but I'll be honest - Icewind Dale and the Baldur's Gate series bored the hell out of me. I don't know what it is, but most CRPG games are just so uninteresting.
I'm so torn. The lore and gameplay ideas sound astonishing, but then I remember what the gameplay will be like (after seeing the screenshot) and it just makes me want to doze off. I just don't want to buy a game I know I'm not going to get into down the road.
Despite this, I'm very happy for Obsidian's success with this kickstarter. They're clearly very passionate about it, and it'll definitely show in the game once it's out.
If it's any consolation, there's going to be a lot of non-combat stuff in Eternity. BG and IWD were largely combat-focussed.
