Hiya.

I can also vouch for C4. I was one of the first adopters (back when there was only one price and it was for "everything, forever"). I've seen it grow, and knowing Eric, the pace isn't likely to change. That is, it's a good pace, not too slow, not too fast. Eric also is probably one of the most receptive, helpful and honest developers I know. He doesn't promise things he can't deliver, and when he gives a "likely date for release", its pretty dang close...and if it's not because of some gotcha-bug, he lets everyone know what it is and how long of a delay. Very open.

Seeing what the C4 engine has planned ( http://www.terathon.com/wiki/index.php/Official_Roadmap ), I'm *really* looking forward to it all! I'm not a programmer, so I haven't done much more then just poke around and keep up to date on the engine...but once some of the new stuff gets implemented, C4 is gonna be tough to beat!
