I mainly play EB but there are some terrific mods out there, IBFD is very good but a problem with the script means i had to revert to an earlier version that only uses 2 turns per year, its still a great mod though. Also its related mods are good .
RTR 6 was my favourite mod for a long time but has been well beaten by EB and seeing as its the same time period theres no point in playing anymore.
Paeninsula Italica looks very promising, the beta has just been released but its not complete yet(for instance all the cities have the same population etc, there are some great units and a superb map of italy though.
Stainless steel for M2TW is pretty good but i dont like how archers are so weak. and i am anticipating the release of King and Country(ECW mod) the previews are excellent and it will be released about november.
