Even without mods this should be feasible, I'm thinking about a template where picking strategy matters a lot.
How about Biomes with 1 pick per person, and similar cards as the 2v2 version? When there is a clear difference in level between the 2 teams, most games would be over in 10 turns (although chances are you'll have this one team member that wants to play until elimination).
I’ve posted a couple and only tested in single player (so doubles chances of winning a Ferrari :) ). Both the picks and how the moves are played are very important, otherwise you’re waiting to be eliminated.
I know how to make a highly skill-based NvN template, but it would need a custom mod & a custom map to work. @alexclusive, does the Ferrari offer still hold?
No mods? Nevermind, then. Custom map is a map which would need to be made specifically for that template and probably wouldn't work outside of that template/ mod.
For anyone else who doesn't understand, the offer is in relation to the Template Competition run by Glory to Czechland somewhere further in this forum.
