Good reviews, guys. I'm not in the market for more games at the moment, but
Lifeform is tempting, since I'm a huge Alien/Ridley-Scott-when-he-could-direct fan, too.
Glad you liked TEZ. As noted on the forum, I'm a pretty serious fan of the TE series. I think what makes TEZ was Gamelyn's willingness to fully engage the themes (and memes) of zombie films: The nine different goals are all standard zombie film fare; the player characters are archetypes from those films; the setting is a mall like Night of the Comet; etc. When you take those thematics and marry them to Almes' typically tight designs (as you mentioned, the cool interplay between ammo and health determining your survival with two tokens on your player mat is a highlight), it hits all the right notes. Adding the visuals of meeples carrying around chainsaws and golf clubs is just the icing.
The other games in the TE series are the same way, in my experience. Al is right that Galaxies is an abstraction, but I think there's good gameplay there, despite that. Similarly, I wouldn't recommend Western if you go in expecting that it's going to be like Western Legends, because it's an abstraction like Galaxies. But, again, there's a lot of game there and a lot of depth. And, like TEZ, all the different player characters have different abilities to provide variety and differing combinations each time. The 'bullet dice' are also a nice touch.
Their next release is Tiny Epic Tactics, which looks brilliant and appears to have both a lot of game and that more visceral stuff that Al appreciates.
