Though I'm interested on account of the in-game fighting being done more or less around the corner, I'm worried about the "shooting at/getting killed by pixels" that also made more realistic mods for BF1942/BF2 difficult to play after a while and the maps potentially being too big.
40 vs. 40 sounds nice, except when you think about how about two regiments/brigades would be doing the fighting on the in-game maps.
Why they would invest so much in realism, yet include British armour north of/near the Rhine is also a bit beyond me.
There are definitely some bugs -- what I've seen its mostly in some parts of some maps and not universal. The inclusion of British Armor isn't unrealistic for Market Garden as a whole and the game is going to cover south of the Rhine as well plus the game is really only in its early stages in terms of scenarios.
Size of battles -- well with respawning forces of at least reinforced company size are fighting and given the mortar support and vickers mg its more more like regiment (Brit style = Battalion)/battalion level. So the battles feel big even on big maps and there is space for armored moves and jeep recon and son on.
As for what actually happens in a battle -- last night I took over a section that was scattered and leaderless after some gamey problems. I happened to have a Bren gun at a critical intersection and (here's a bug, I think) becoming section leader cured all my wounds and refilled my water bottle. So i popped upwith the Bren and the Commander got me on the G (command line) and said "Find out what's holding up the infantry on that road"...I was in position and cleared the road and my section tightened up, went into the objective and took it. I was hit at some point in all that (tank fire -- possibly friendly i think) but got back in time to help clear the town with a sten gun and grenades.
In my experience, the game is very different from the more standard FPS games in its direct effects in terms of what you see and do. You don't hunt pixels, you wait for coordinated fire, and smoke and attack with a lot of other players. Very NEATO at least to my mid-60s kid aesthetics.
