As the most enjoyable times I had with Mtw engine are when Im playing Ntw, Atw and now Pike&musketier v1.0, I really dont mind they focus Mtw2 till 1580, that will probably allow for even better versions of above mods.
About Rtw, I really hope they can keep the look while making Mtw combat style.
I was a very disapointed Rtw player (I pre ordered the game, instaled, played the toturial, started a campaign and was terrible bored by the asteroid pace of the units, unistaled the game more then a year ago and only after this Christmas I give it another try, this time much more enjoyable with Rtr or Biv1.6 Atilla's mod).
So for Me, Mtw2 will hopefull allow for real great mods to be done on the time I enjoy most, from the birth of My country, Portugal (That I hope this time can be playable, not a freaking spanish province, for Christ's sake Portugal is independent since 1143!!!) till the Xix century with the look of Rtw and the feel of Mtw.
