It was brought to my attention today that a petition has been made for Rockstar Games to make both GTA1 and GTA2 open source. For those of you not familiar with programming terminology, this means that the source code (basically the code that makes the game work) will be made viewable to anyone who wants it.
This would be invaluable to modders and programmers alike, who would be able to make modifications to ultimately improve the playabilty of the games much more easily than before.
Topic starter drwbns sums it up well.
Creating enhancements such as improving gameplay physics, weapons, and netcode could be a start and would show the GTA community contributing back and showing their support for old favorites.
Thanks for the support everyone!
