@Bio - You've got mail!
@ace - Yeah, thats good to hear and TNT4 is already in developement for almost a whole year... even a bit longer since I started with it a few months before KDiZD... nevertheless, I'll give my best to not disappoint you guys. And yes, after this final TNT piece, I won't stop working for that series... the reason is quite simple: I am finally out of ideas! Everytime I created another TNT part, I made it even better then the first one with some new innovative things never seen before, and I just could do this, because the Quake (and equal) resources made me think of new stuff while working on a precessor. And now, with TNT4 I have finished what I had in mind and - as anyone knows - you should stop when it's the best time of a piece and I don't think I can make TNT5 better than all the others.
After TNT I will concentrate again on KDiZD and meanwhile finish the "Tower of Suffering" which will all be released in 2006. Afterwards, Stronghold and Netherworld still needs to be finished, but I think, that will also take another year or more

So, no new series like TNT, but maybe another random map like CotD or ToS!
