I'd have to argue (hi btw
), that all good things must come to an end. The work done on HPB_Bot was amazing, introducing bots into the HL engine was no easy task, making them WORK was even harder.
These days though, bigger and better bots seem to be coming round the corner based on HPB, and from what i've seen, there isn't really any other way to improve them and bring them back to the 'GodLike' status they once were. Maintaining the bot from this point would be trying to give someone whos been dead for about a year CPR (No offense intended). HPB has become one of the best educational resources around especially for AI and bot developers alike, but imho, the sunlight has been stolen, and theres not much short of a miracle that will bring it back
Just my 2c
