FO 3 imo.

I've never played ME2 but if it's anything like 1 I probably wouldn't like it.

The biggest issue is that you don't get free-roaming after you defeat the campaign, so you'll need to do all sidequests before the final mission if you want 100% played.
They changed this with Broken Steel didn't they?
