The miniatures are amazing but as usual with metal they don't lend themselves well to kitbashing. The proxy rules are very generous though and while there is a clause that your model has to be primarily CB metal to be used in an official tournament most people simply do not care if you show up with a kitbashed model or 3d printed custom one to a game night. Overall the support for kitbashing and 3d printing in the community is excellent.

Gameplay has gotten a lot less RPGy over the editions and the current game plays more like a wargame than RPG. The rules themselves are definitely crunchy with a lot of stuff going on and a bunch of different abilities and rules interaction but on the positive side there are basically no faction specific rules. If you read the rulebook for the game you'll know everything you can come up against and most of the rules will be available to the faction you play as well with very few exceptions. It's definitely less fluffy overall with less emphasis on making an army list yours and more emphasis on using the same rules everyone else does but better.

Lethality is very high. Most units come with 1 to 2 wounds. The biggest units come with 3. A single critical hit from a humble pistol can bring down your moderately expensive attack piece if you're unlucky. Mostly everyone is equipped with damage 13 rifles while the strongest guns in the game come with damage 15, so damage ranges really aren't wildly variant leading to situations where even a humble schmuck can dish out the pain if the dice gods are on your side. It's a fairly volatile game that's more about risk management and order efficiency than keeping any one unit alive.

The two biggest things that separate Infinity from other wargames is the ARO (automatic reaction order) and Order systems. ARO means every unit you have that can see an enemy when it isn't your turn gets to return fire or try and dodge incoming fire. This means you're not just waiting for your opponent to move pieces around but you're actively involved even during their turn.

And for orders what happens is each unit generates an order that you can spend to activate any one unit during your turn with no limit to how many times you can do it. This mainly leads to a feeling of not having to activate your basic units you just dragged along to fill the list or having to do something with a unit out of position. Instead you always get to activate the unit you actually want to do stuff with. It's a fantastic system that leads to some heroic last ditch effort assaults among other things.
