Evo is entirely freely licensed, cc by sa for art. I should use cc0 tbh, cause I don't care, to be quite frank.gajop wrote: Art (models, textures, etc.) might not be open sourced, but it probably already isn't in a number of other projects, including some of the main ones (e.g. ZK, Evo).
Old tech holding the engine back isn't really that valid of an argument anymore. Thanks to Floris and myself, BA has gotten a violent shove into modern times and is a drastically better game in every way.
Realistically, not a lot can be done about the models, assuming that BAR's anus remains firmly clenched and a lot of the unit scripts leave a lot to be desired, but pretty much every other part of it has absolutely been modernized (except the armour class system which uses spring's awful default system, but most of you would likely consider that to be "modern").
