Very impressive for a first version.
I really like the idea behind this mod but I think it needs a little polish to really bring it out. The most ovious thing is that many of the textures need some improvement since they are too plain (sometimes just a single colour).
Unit design is really nice and creative I especially liked the opposition Devourer, Big Wolfen, Welder and Stormbringer, the mother land Harvester and the coalition Stormchaser.
Music is okay at first but quickly becomes repetitve. There are basically no unit sounds other than gunfire when fighting.
Balance is waaay off atm, coalition is best followed by opposition and mother land trails far behind. I like the idea of the harvesting units but the pace of the game becomes excruicatingly slow when playing mother land or opposition. If you're playing against coalition you might as well not bother since they will win every time. Also the A.I is pretty clueless about what to do other than churn out grunts.
There are also a few other small things such as only having one map with the mod, quite a few spelling mistakes and a somewhat bland tileset.
Having made a faction myself I know you must have put ALOT of work into making this. It is certainly the best Glest mod in a quite a while. Whilst it may not be as polished as some single faction mods (Egypt, Woodsmen, Elves), it makes up in sheer quantity of three large factions. I really hope to see an improved version of this in the future
Also my advice to anyone else who hasn't downloaded this is to do so, you won't regret it!
