Yep, definatly not..
I have discovered few major problems with my code. Those are kinda of problems which requires some changes in the deepest core of the game.. That's why I'm considering of rewriting the whole engine.. That would postpone the release a bit but in the long run, I think, it would help me in future patches not to mention stability of the game itself.
I was planing to introduce the "real" multiplaying in the future but if I start working on new ( improved?) engine, I might aswell implement multiplaying there. I think the rewriting wouldn't be so time consuming since I got good part of engine code well coded and working, so on those parts it's just copy&paste.
