>>43340324I ran a game like this a... well... let's just say a VERY long time ago.
We booked the weekend for about five of us at a friend's house. We all brought sleeping bags and party supplies and booze. I was Dungeon Master.
The rules were simple. Don't take the game too seriously. When the game is over on Sunday evening, it's OVER. The whole campaign is friday to sunday. Everyone creates at least two characters. Any system is fine. I'll make them all run together in my head, which once I'm well and truly drunk will be hilarious. The group got a bag of holding for their loot, and if someone passed out, it was assumed that he was in stasis in the bag.
So we had about a dozen characters from three publishers and seven or eight game systems. The Shadowrun PC was eliminated almost immediately. One guy was so proud of his ruthlessly min-maxed clan mechwarrior... until he died at the touch of a Red Cap changeling another player whipped up on the fly, when the red cap used his haywire power on the clanner's mad cat. Several WoD characters showed up, which was great because D&D monsters grant D&D-levels of XP, and a five hundred XP orc will shoot the world of darkness character's power level into the stratosphere.
No this doesn't make much sense. Yes, we had a blast. We were drunk as shit by this point.
The game was finally won by a combination of two players. One was a "death knight" (no, I don't remember what system he used) but he cast a fertility spell on the other guy's mokole character (were-alligator from WoD). Mokole get extra dice for every child they have. So the mixed army of mokole children, the mokole PC ("mamma" aka godzilla) and the death knight rampaged over the world. Whenever a mokole was killed, it was rezzed as a skeletal mokole-lich under the death knight's control.
Chaos conquers all.
Midway through, we'd stumbled to a local coffee shop for snacks and partially sobered up. I think that was a mistake, in retrospect.
