Heroes VII

multiplayer (too slow development).

Well, for this, there's the Governor with economy skills. If you spend some experience points on him, developing him first to Architect, you save money on constructions, and then further to Town Planner. And it also depends on the map; one thing is a random map, another is these "balanced" fixes with obelisks costing 50k experience. On some fixes, you can have elite creatures and two Governors on building (economy) and recruitment/growth (diplomacy) by your second week. On random maps, it's a bit more complicated, but even there, you can sometimes really shine right from the start.
