In short, sorry to say this but I don't reccomend it. To sum it up:
1) The outcome of the battle tends to depend far too much on luck with dice rather than tactics, using terrain etc. The game tends at times to eb so random as to seem a glorified game of craps with toy soldiers in the background.
2) Units are generic, you get almost no ww2 "chrome" in this game. Maries and Japanese infantry are the only exceptions that stand out.
3) The business model is costly and player-unfriendly. Its not so much a F2P game, It feels more like a free extended demo.
I played this with a friend - we are both old time wargamers (Advanced Third Reich, Squad Leader, Steel Panthers). We came to this expecting a beer&pretzels sort of "Baby's first Squad Leader" game. I don't mean it in a derogatory manner - in my opinion there is nothing wrong in making a simple or fast-play game on a popular topic, in this case tactical WW2 combat.
Memoir 44 failed to deliver though. Yes, it is simple and fast. However it also lacks historical "chrome" and all the unit types feel far too generic (german tanks in Normandy have same stats as allied tanks etc).
The worst thing about it is that it is VERY random in combat outcomes. 9 out of 10 games both me and my friend walked away with the mutual conclusion that it was luck that was the decisive factor. In this game, your decisions, combat errors or tactical mistakes feel to have very little impact on the outcome - luck means much more.
We've had situations when infantry charged madly into the open field and shot to pieces an opposing infantry squad (same stats) that was defending a bunker. And no, this was not a point-blank assault on the bunker, we were shooting from many hexes away. I'm ok with such situations happening "once in a blue moon", but in memoir 44 this happens all the time. Much more so than in most ww2 combat games we've seen - here everything depends on how the dice rolls - terrain and equipment don't seem to matter all that much. For me this is an absolute joykill.
Let's get one last thing straight - calling this F2P is somewhat an exaggeration. The free part is more of an extended demo - you have a limited amount of gold that allows you to play the game a limited amount of times except for several small free scenarios. After you run out of gold, you will need to pay money for each scenario you play - multiplayer, single player, doesn't matter each time you will have to pay. This does become a probem as each scenario is small and these play fast. IMHO this is not a fun business model for me as a player.
