I've been playing the new Beta whenever I've had some free time, for a while now, and like Aaglo, I don't really have any complaints. I like the new rally point system, even though it's annoying not to be able to upgrade any of my race units.
I'm slightly annoyed by the research limits, but not enough that I think it needs to be changed (or, at least, changed on anybody's Mod besides mine).
I still haven't gotten past the second era in any of my games yet, so if there are late-game changes I haven't really experianced them, so I can't comment on them.
A stupid remark on race-symmetry:
In the current version of MoM there is a race-required navel unit for elves, humans, and lizardmen(the Giant Turtle,which happens to be my favorite naval unit in the mod); this means that the resources are
slightly unbalanced. If you added a navel unit or maybe a special unit of some other kind for orcs or trolls then the "bonus race-units" would be symmetrical over mage types (Life, Chaos, Death, Nature), even though the resources would still not be exactly symmetrically distributed w/ respect to each race resource (elves, dwarves, humans, etc.).
But that's not neccessarily something that needs "fixing", because I don't think that every resource has to
exactly as powerful as the others, slightly un-even strengths lends itself to more variaty.
Anyway, for the most part, the mod still looks great, and it's nice to see some of the new Aaglo units in action. Btw. as regards your Mod surviving a lapse in development (this comment is in the WH thread), I personally think that MoM could and should survive, even if you after you are no longer able to devote anymore time to developing it. It's unquestionably (in my opinion) one of the best 2 fantasy modpacks for Civ 3), and is in my top 3 mods overall.
So don't feel like the mod is going to sink into total obscurity even if you can't devote much time to developing MoM. I look forward to the final release of v 2.0, but don't want to put any pressure on you to finish it anytime soon, becuase you've gotta have your priorities straight, real life always comes first. It's just nice to know (or hope) that it will be done eventually, and provide a sort of final gloss to one of the greatest (at least in my personal opinion) mods of Civ III in existence out there. (and besides, it seems like Clearbeard will still have some stuff to add after you finish, so the mod won't stagnate completely)
