You got me all wrong.
I don't consider combat as "fun" , only to let the party survive.
That's why I don't like "Action-RPG's" that much.
Fair enough. For me, the fun comes not from the battle, but from assembling the team and tools for the job, making a plan, and then seeing how well that plan works. I liked IWD2's battles because they were a little complicated.
That's different from a game like Diablo (which I don't like) or DS because those battles give me none of things I find fun about combat. It's just random incessant clicking until something expodes. I need something to analyze and figure out. And sure, when there isn't some reason behind the battles it weakens the game.
It's not either/or for me though. I enjoy all kinds of games.
