man libtw2 was made so precisely, all errors, warnings, all netcode stuff, map processing, multiprotocol support etc etc. heinrich made enough to run a server, by their hands. last piece of the puzzle were 1:1 tw physics, since you have no physics, you can't have prediction, no playable server (for people with default clients) and no client at all. heinrich indeed did a fundamental work, don't underestimate it
