To all the people saying they should release server source code: You don’t even need to do that (as nice as it would be). At the very basic level all that is needed is:
- remove DRM (which probably cost more effort to add in the first place)
- a description of the API for any online components (which any decent dev team will already have internally documented)
I’ve downloaded some old PS2 era games. Some of the gameplay is quite dated, but I really enjoy the retro feel of the environments and graphics. Perfect photorealism isn’t always necessary to enjoy a game. I’ve been playing Burnout and Ghost in the Shell SAC.
