Do you have a verdict on the game as yet?.. been considering over whether I should purchase it, on a couple of occasions, when its been on sale.
My verdict is definitely positive. It's the most "real" feeling wargame I ever played. The attention to detail is staggering, and weapons systems seem to work as they should. In Combat Mission, it feels to me as if troops are actively trying to miss, and many weapons lack "punch", sometimes taking ages to hit anything even at short range. In Mius, small arms are really deadly at 100m.
Infantry in Mius also behave more intelligently in some situations than in CM. For example, if an enemy tank is driving towards infantry, they will actively run out of the way to avoid getting run over. Sometimes, they don't make it, but generally they are good at it. They will also throw all kinds of AT weapons such as mines, grenade bundles, AT grenades etc. all modelled in detail, not just abstracted by chucking standard hand grenades.
Tank damage modelling is also much more detailed and advanced than in CM. Tanks get tracks blown off but keep going for a while with the track trailing behind, they leak oil when hit in the fuel tanks, etc.
In one battle, I was frustrated that an enemy tank seemed to shrug off all hits and just reverse out of danger. After some moments I realised that it wasn't reversing.. it was knocked out and rolling backwards down a hill because of gravity. It slowly rolled all the way through a village, paving a trail through it by crushing through trees and fences, before finally coming to rest in the valley. Next battle, the wreck was still there, and so was the trail of destruction it left behind. That kind of thing makes it difficult to go back to Combat Mission.
I could write much more about how much more detailed this game is compared to CM. It also has some drawbacks though. Mius is better with combat in the open, whereas CM is more detailed in urban terrain. You won't see infantry take cover behind low walls in Mius for example. But on the other hand, trenches are way better in Mius than in CM. Etc etc.
Despite all the good stuff, it does take time learning how to play Mius. Especially three things make it seem more difficult than it really is:
1: The interface is complicated. But it has been improved a lot since I picked up Operation Star years ago (and got a refund because it was a mess).
2: The manual is poorly translated and lacks a lot of info about how things actually work.
3: The game is still in active development, which on one hand is good because it means it's still improving, but on the other hand, it means a lot of what you see in various Youtube tutorials has been changed later and no longer applies.
Final verdict: Not everybody's cup of tea, but definitely worth picking up on sale and trying out.
