Hey welcome to the forums. Seems like no one answered you. Even though I don't play MTW2 (my computer can't handle it) I have done alot of research on MTW2 mods in my spare time. In my opinion I would say Broken Crescent is probably the one of the best. It is highly detailed, lots of new units, stats for units are good, very historically accurate, gameplay is good, and it is a complete modification of MTW2. It is very similar to Europa Barbarorum in that it is a very complete mod. The only problem with it is that it is more focused on the Medieval Middle East, so I don't know how much that conflicts with your liking of the Medieval Euro. Although it does feature the Kingdom of Jerusalem and Byzantines which are European factions and have European-like troops avaliable. If you don't want Broken Crescent than go with Stainless Steel, very similar to Broken Crescent in all that I mentioned above and it is centered in Europe. I think it would be a good first mod for MTW2. Sorry for the delay in response hopefully you'll get this message. I was just wondering if anyone would post a question like this.
