I just think froma basic point of view the only 2 things missing are force feedback and alpha channels /transparency support.

I would be happy with those 2 added. Ok so it is gonna be basic games but I have had a lot of fun with delphix and for beginners it is a great starting point, me being one of them.

I never would have made a game without it or even expanded my knowledge of programming. So, I wouldnt say it is in the dust and worthless at all
