I have a large collection of 15mm WW2. US/UK/German.
Every time a new edition of Flames of War came out it would be added to. I've bought more versions of the game than I've played it! The one and only try at 4e of FoW seemed to me to reveal that the game system was in a mess - unit stats not available, incoherent publishing sequence and structure and so on.
So, where should I try for a good company [ish] level game?
