Would hat mean that anything I play in HoM&M V, Dark messiah or VI is just a whole other irrelevant story (irrelevent to previous games)?
Any official news on linking everything together in later games perhaps (since the reboot takes places in another world)?
HOMM4 (and its expansions) is the last strategy game in the old NWC Might & Magic universe. Might & Magic 9 is the last RPG game in that universe. HOMM4 probably/maybe comes first in that universe's timeline, then M&M9, then the HOMM4 expansions. But at that point, I'm not sure NWC was doing as much to integrate the stories as they had in the HOMM2-3 / M&M6-8 era.
