The dynamic of Splendor completely changes at the higher player count. My strategy usually revolves around the nobles and denying critical cards to others. It's not a deep game, but we've enjoyed it as a starter.
You might want to get the Giant Squid expansion for Survive, it really changes the feeling a bit. Squids can pull meeples from land as well, so no one is safe. It quickly turns into a race to get ANYONE to safety. My wife refuses to play with it actually.
Have fun with Robinson, it's a blast. I just ordered the King Kong scenario, so I'll report back once it arrives and I get a couple of plays.
I'm hoping to get Quantum to the table this weekend, and maybe a couple more games of Core Worlds. We've been playing a ton of Star Realms as well.
Have you played anything outstanding lately?
The King Kong scenario is actually the reason I pulled out the rulebook to finally give RC a play!
Quantum is pretty cool, though check your dice. A lot of them were warped and oily. The company replaced them very kindly (and sent a promo to boot).
And, of course, I can't stop pimping Star Realms.
I recently played Run, Fight or Die which I think is a pretty good dice based zombie game. It really sells the impression that you're just trying to keep ahead of an ever growing and massing horde. Good sense of humor, too.
I also played Darkest Night (solo), which I think is pretty neat. Not as fiddly as I was imagining, and a nice theme added to a Pandemic style keep-shit-from-getting-out-of-control co-op.
Hull Breach is like a space skirmish with cards. You build up your base and forces (putting marines, fighter ships and upgrades on some bigger ships) then send them at your opponent. The build up seems to take much longer than the actual battle (the game can be over in one or two rounds, actually), but I think most of that can be attributed to learning the game. I'm looking forward to giving it more tries.
Hoplomachus is a gladiator game which has the unique mechanic of stacking health chips under the characters. This not only gives you very useful information at a glance, it's also pleasingly tactile. The game has some cool mechanics, too and is fun to play.
Finally, though I'm sure it won't be everyone's cup of tea, I have really been enjoying the Dark Gothic deck building game from Flying Frog. It's Ascension style, but with some twists. For example, there are three different resources (and a generic that can be swapped for one of them), and each character has a starting deck with different combinations of those in basic cards. For example (and I'm making this up), the Priest might have 8 Spirit, 3 Cunning but only 2 Combat, while the Pirate Lady has 6 combat and a more even mix of the other two (I think the Priest has an Honor card, too, which gives a generic and a card draw). They also have special abilities. The Priest can swap his spirit for combat when battling minions or villains, for example. There are three main, randomly drawn villains to work through, and they all have global effects as well as effects that trigger when you fight them. And the center line is filled with gear, events, locations, minions and allies. All of which do different things and cost different amounts. It's all decently thematic and a lot of fun.
