I totally agree. Especially with the Cynical Imp part, it really should be a skin. I mean, the model already exists, why not put it to use? =]
And about this year's post, there actually are some nice ideas I wouldn't mind seeing in the game, like gold shrine tax over time, Beastmaster refusing to eat raw pigs (creature personality trait right there!), "Jackpot Dinner", and, heck, maybe even Lighting unable to strike same tiles twice. Maybe with a bit of cooldown on each tile?.. =D
I really think The Cynical Imp and Democorn as well as some of this years April Fools ideas should be added to the game as unlockables and part of a new game mode that can only be played once the campaign is completed and can't be used in multiplayer. This new "crazy" game mode can do other things like introduce wacky effects and modify game physics (if WFTO has any) and give creatures big heads etc..
Either way, I would at least like to see the Cynical Imp and Democorn in the game.
By the way, the video for the Australian edition cracks me up every time I see it. Good job on that.
