Themepark RPG?

[Professor Cena]

I've been looking for AGES for a decent Theme park type MMORPG, similar to Rollercoaster Tycoon series, and this is the closest I found, it's not ready yet, but looks promising to be honest and I'll definitely be playing, anybody else seen it? What do you think?

Is.. This a flash-game or a MUD?
