Anyway, why release the first version for entrenchment? wouldn't it make more sense to do it for trinity or the original game because more people are likely to have them?
Well, people with trinity have Entrenchment... Trinity mean the original game and the two expension pack...
About Diplomacy, for the time being, it is not really a good choice for mod... mainly due to Diplomacy using a lot of ram and hiting the 2gb limit very fast... this will maybe be resolved with the "in progress" patch for diplomacy...
By the way, i think that in the Halo universe, it is more about "seek and destroy" that about long diplomatic negociations !!!
