Monster Bash is a game, sports league and bloodsport. Players design animals and monsters and pit them against each other. Gambling is common, and several genehackers fund their work with a Monster Bash career. The matches take place in simulspace, but successful beasts in the realistic league are occasionally grown for real, as smart animals.
Two informal leagues have emerged. A realistic league, using atomic-scale accurate simulspaces, and an unrealistic league, allowing considerable leeway to designers. The realistic league is a brutal bloodsport, realistic enough that the simulated animal brains experience real pain. For this reason the realistic league is limited to Extropia, where it enjoys the patronage of smart animal developers looking to test or show off their newest creations. The unrealistic league is more popular and widespread, both because of the lack of ethical concerns, and because the league allows for fantastical, showy monsters with impossible abilities.
Anticipation is high for next week's showdown between the ferocious grace of Claudia Ambelina's mantis ballet and the brutal slapstick of Shiffer High Energy Laboratory's plasma toads.
