I am around 3DGS 4 years ago but more active recently. I bought an A5 Com and soon I bought an A5 Pro license from someone but very bad timing, 3 or 4 months later A6 released. I am so upset and haven't create anything with A5. I want A6 but can't afford to buy the upgrade "again". So I look around other engines, and of course spend(waste) a lot of money in licensing, I look more like a game engine collector.
I lost motivation on game creation and spend all my spare time on other hobbies, including learned J2ME and created a small mobile game.
So When A7 announced I can't wait to upgrade, and I think it is a perfect timing. Now I can transform my idea into reality.
