Good idea
Yet after, after Dom 3 ... Wesnoth is deeply lacking. Having played both intensely, I'd have to say Wesnoth is relatively easy to play, easy to figure out, somewhat lacking in depth, and in many ways, simply brain dead. I just don't really play it anymore, my son does, but I think it has played out for me. OTOH, Dominions 3 is so intensely rich that once the balance is evened out (either by various mods or by simply discarding the "weaker" factions) it is a challenge with no peers. And a further step up is the MP games. Once you have sort of figured out the SP version, MP takes it to an entirely new level. Dozens of races, infinite variety in Gods, hundreds of units, and spells, and magic items and weapons all sorts of variety. There is no "right" way to beat the game. It is, as with real life, entirely situational. This coupled with a game structure where anything is possible, anything, makes for a massively rewarding challenge. Wesnoth was mastered in an hour. I still don't know if I've mastered Dom 3. As with Wesnoth, highly modifiable.
