You'll see some of the Osprey games at Great Hall quite a bit. I like the Fleet Action game - best naval sail game I've played. Simple and bloody - good stuff. Ronin is a lot of fun and now I have dozens of Samurai, Sohei, Wako and some rainbow Ninjas.
Frostgrave is gaining some attention for sure.
I've not played Lions Rampant, but have read the rules and it will do well for historicals. I know guys that already want to use WFB minis for Frostgrave and Dragons Rampant. Not sure i'd call any a tournement game by design, although Lions/Dragons Rampant could fit there.
