Yeah. I think there was a thread floating around here somewhere, but it'd be old enough that a new thread probably isn't too bad of an idea.
I found it fun, if a little slow. Grab the trunk version if you can. Development and releases are slow as hell, but usually there's some nice features in the trunk.
2.5.something has some good balance fixes, including weapons and encumberance effects (no more do-everything-including-medic soldiers). There's also a slightly different tech tree, probably more balanced. It's harder, strength stats mean a lot more (and you'll want to train it by carting heavy stuff around, which is sort of weird with the encumberance system trying to make you *not* do that) and weapons/skills are better balanced. Sort of.
Not sure if they've fixed late-game TUs and reaction fire on the aliens, but it makes small/quick weapons still have some relevance. I actually like the weapon balance in that even older weapons still have a use and a small upgrade path (although some are completely irrelevant in late-game due to armour and resistances). Combined with encumberance and skilling, it makes your snipers good at sniping, assaults good with assault weapons, but excellent soldiers can still multi-role a bit (or be levelled into it). Many weapons are side-grades rather than clear upgrades, with different features or uses than just bigger damage. Resistances come into play as well, but you probably won't ever hit a tech-gap that rocket launchers, grenade launchers and sniper rifles can't just manage to get around until you catch up in that area. Heavy armour and resistances do make basic small arms redundant though.
Aircraft and the weapons/systems for them are your only major tech stumbling block, so research them ASAP (like any xcom game).
All-in-all a fun if somewhat slow to play game.
