BYOND is great potential wasted on pitful DBZ and Naruto games with a bunch of lame-ass "icon chat" games.
Most of the unique and good games are generally unplayed, and even then, any of the decent coders make these lame cloned RPGs or chat games.
BYOND, to a certain extent, can do 3D as an example. Of course, there's no point in using that capability, but it still shows that no one is truly taking advantage of the engine. Most of the natrual "engine ldimensions" can somewhat be skipped over with some smart coding, such as the tile-based movement. I have never seen any coding breaking BYOND due to pushing the limitations or anything - then again, some of my favourite games are text MUD-like games or your unusually concepted game (Lexiconomy, that one search engine game), both of which really don't use much more than text. But it's still the easiest possible way to build a internet based game, so yeah.
I quit BYOND some long time ago since I felt that the (at the time) new beta was basicially the last straw in them taking BYOND in too much of a commercial direction. I remember the old BYOND, and it was so much better back then than now.
Chao Chatterz sucks. It's just another lame icon chatting game with Chao as the default icons, which is pointless since you'll probably just change your icon to some crappy Mega Man or Final Fantasy recolor anyways.
