HOMM III - WOG (hot seat)

[Holly]

Me and some friends are going back to revive some old school days of battling out in hot seat mode to see who can outwit who in both might & magic. We are going to play 2v2 with no computer opponents. So, a kind of pvp mode. My question is: How big a map is good for this for game not to become boring and tiresome? I was thinking medium with underground?
We are, of course, playing random map, with random starting towns, heroes and bonuses. So, luck will play a great role in many aspects. But we're all heroes veterans and love playing against the odds just for fun of it. Currently we are negotiating about which rules from WOG to include. We're going for minimum of things to include just to make the game as simple and clean.

And advice welcomed and appreciated in advance.

Great forum and site btw.
