It would be wonderful if those who have their ideas utilized in Demigod could be listed under a "Contributions" or better (according to scope and import) field in the game manual at time of release. T`would be very cool.
what would be even cooler:
A pet, icon, item, minion, samurai flag, skin, weapon, etc. that is given to Gamma/useful testers that doesn't necessarily do anything too awesome, but definitely looks awesome compared to vanilla models. The sort of thing that ships with a Collector's Edition, but unique and just for Gamma testers...
