Going beyond Bioware's games, I like how story-based games in general are far more likely these days to allow the player to select difficulty level. This opens up a much wider range of game to me because some play styles just aren't my thing and sometimes I only want to play for story while moving through as quickly as possible. Although, for fantasy-style RPGs like the DA series I usually want my nightmare play-through too.

Unrelated: can you recommend a few good puzzle games? Preference for iOS because that's my primary casual gaming platform, but I own just about every other platform/OS under the sun so any good puzzler reco is welcome.
