I'll preface with the fact that I respect anyone that puts their time and effort into improving FA and FAF, and I have no doubt that this is the intent of the rks mod developers. This being said, there isn't a single aspect of this mod in its current state that I find appealing.
Most importantly, some large unit death statistics are being altered. For example, a megalith dying currently does over 33000 damage in total, up from 7500. Fatboy is quite similar. Much of this damage is being done to the wrecks as well, lowering the reclaim value of these units by several thousand mass.
Personally, I don't find a single one of the explosion effects to be more attractive than those of the standard game. The majority of them look like out-of-place sprite effects that were ripped off from a Game Boy Advance game like Golden Sun. I'm running maxed out settings on 1080p with 8xAA and bloom on. At no point in time have the normal death explosions struck me as inadequate or requiring attention. However, if the game incorporated rks mod explosions in its standard form, I would find myself wondering what THQ was thinking. Am I the only one that thinks bright green blobs and cheap-looking clouds of flame contradict the normal style of the game?
Is adding goofy effects to the game really a primary concern of the community? What about fixing all the connection and desync issues, expanding the player base, tightening balance or improving hardware lag? There's a lot of gifted people here that would like to make faf better. I feel like your talents might be better utilized in other areas.
