With all the different Tdm, Zombie, and other minigame gamemodes out, it's all getting kind of cluttered and confusing. I think it would be a lot easier if sort of like slayer, (only sort of,) there was one big Minigame mod. With A default minigame option, dedicated minigame option, minigame favorites, kill streaks, assist kills, an ai system (sort of like Zapt/gamemode_zombie, only more for ai in general, rather than zombies,) maybe custom ai to go with it, and maybe even some weapons and such.
This would eleminate the need for multiple multiple add-ons enabled, like T+T, default minigame, dedicated minigame, tdm, gamemode_zombie/zapt, assist kills, kill streaks, and any other minigame related mods.
I know this would be a very big project, but I personally think it would be well worth it.
