I can take or leave minis. More tactically-focused RPGs play better with them, imho.
My real issue, though is that some of the people in my groups are so dang in love with all of their MagKnight and Dwarven Forge paraphernalia that they deploy the stuff at *every possible opportunity*. Every step through a dungeon becomes a construction event, and players get into the habit of thinking and moving tactically even when we're not in combat.
That and the Dawrven Forge stuff, frankly, just gets in my way. Unless I'm standing directly over the table looking straight down, I can't see a dang thing. Sitting down and looking across, all I see is a dungeon wall between me and my mini. I really prefer to break out the battleboard only if a combat is complicated enough to warrant it, and even then all the scenery I need can be provided by a wet-erase marker.
But I could just be weird that way.
