My current favorite games in no order are
Castles of burgundy
Terraforming mars
Brass birmingham
Barrage
I like games with some economic aspect, plus you get to use chips as money!
Most of the games I really love are easy to teach and play but difficult to master or be good at. The depth of strategy provides a lot of replay ability and they aren't over complicated just to be complicated.
I wouldn't say that TM is an easy teach , one of my favorite games at the moment though.
I've been out of the bgg and board game YouTube scene for awhile now, hadn't heard of Barrage. I'll have to check that one out.
