Yes, it's a very solid tactical combat game. It has room for character RP moments but the meat of the system is in the mech design (which gives you plenty of opportunities to make adjustments to your build) and on the turn-based combat map. It's less crunchy than Battletech (you aren't tracking damage to specific limbs, etc) but IMO the action economy is usually more interesting than 5e - there's a lot more opportunities to build for "when you do X, if condition Y is true, you can follow up with Z for free" combos.
