I still prefer RTW over M2TW; probably because of RTW's interface. M2TW's interface appears odd to me, in particular the way they prevent all the traits from being seen. also I think moving units around in battle mode in RTW seems smoother than m2tw, but that's probably because I started playing RTW before M2TW.
my computer can't run ETW though
I've yet to install any mods, I think I'll go over to the other subforum to see what mods are available.
