love :

* because it was one of the first to help newbies create games with limited coding skills!

* Price

* because i was one of the first to get a3 for free ;p

* Some Tutorials but far from complete!

Hate :

* No Real Book that teaches how to use it. You must create in the dark!
* It needs to support collada file format.
* Med is shite! Use wings3d or buy it (even if wings3d is opensource i am sure they have there price hehe ;)This would be a site to see
* Better animation core is needed. (if med was dumped and wings3d bought then you could build the animation core around it!)erlag or no erlag!!!

i could go on but i wont these are the main things required apart from killing bugs!
