Yep. I like this approach because it allows things like having a tactically interesting battle in a realistically sized room.I find it easier to not think about when I consider the squares the creatures reside in to be abstractions themselves.
Hell, I had to look -hard- for a 'one square is five feet' rule. Honestly, I just run it like I did 'turn length' in World of Darkness. How long is a turn? Anywhere between 3 seconds and 1 minute. It's 'as long as it needs to be.'
You're in a small room, so everyone has to make do with less space. So the squares are smaller.
