They screwed up the war3 Remaster, graphics alone wouldn’t make that big a difference.
I think it would be more realistic if we either paid a reverse engineer to figure out most of the war2 source code or redesign it from scratch. This would allow us to add extra goodies like a Third race.
A traditional mode or enhanced mode where Heal acts as a proximity spell with a better mana ratio, cheaper exorcism, better skeletons, greater slow proximity from mages, etc... Maybe each race has a slight unique advantage for early, mid or late game. KHB probably still has the sc2 engine we could use.
Realistically, Blizzard lost its way when they merged with Activision and Vivendi. Some of us could contribute talent, others would be willing to contribute resources. We would need a solid point man to coordinate all the efforts and gauge the feasibility and time frame to completion if people are down. This would be mere pocket Change for Swift D. RothsChild
