Stuffed Fables, or The Adventures Of Robin Hood (not played the latter but I believe it’s a similar adventure gamebook system)

Deep Sea Adventure

Keyflower is one of my favourite games!
Lords of Waterdeep is a good pure worker placement.

Mysterium - identify the suspect by looking at abstract cards given by a ghost (goes up to 7 players I think; use the original Ukrainian rules!)
Shikoku - interesting movement game, goes up to eight players
Eclipse - epic space exploration and battles, nine players with the expansion (I’ve never played it nine players, it would probably take about a week and need a banqueting table to put it on)

With the Cities expansion it goes up to eight too. Pretty simple to explain and as turns are simultaneous the extra player doesn’t add any time (unless they are particularly slow)
