It's a Wonderful World (up to 7 players with the expansion )a kind of 7 Wonders with resources and combos. Actually, we don't play 7 Wonders anymore.

Condordia Venus (up to 6 players) very euro-style, move your workers on the map to build warehouses to gather resources to build more stuff and buy more actions..

Root (up to 6 players) very asymetric strategy game. It's so asymetric that each faction plays a different game.

Demeter and Cartographer (almost illimited number of players) like tons of other roll and write, they are the perfect games when there are too much players for other games and you don't want to play a party game.

Also, lots of games are fine if you add extra players with a few tweaks: Mansions of Madness, Pandemic, Res Arcana..
