I'll be real honest with you buddy...
220Mbs of Movies + 80Mbs of MP3 makes it for a thin mod (by my definition)... although the general context has been altered to immerse the player in the AVP situations - that's a given.
But when it comes down to giving us more "alterations" to the gameplay itself, there's nothing in there that modifies other stuff than some usual Race(s) Images & Logos. That's only me though -- as when i need to watch Action flicks i simply pull out what i want from a stash of DVDs or, when i urge to listen to some favorite Rock'n'Roll songs from a HiFi system that drives 125+ PowerWatts through a set of 4 customized giga woofer speakers i simply crank up the volume from CD quality recordings.
Sorry if the above sounded a bit critical... but, if i needed to do a better job with the CoSH techtrees so should you consider giving us more MBs (somehow, of gaming value) for our bang.
From anyone else's perspective - this might, indeed, be an excellent mod.
