I really like that Steam is doing these. It seems like a good way to get eyes on these games and build some awareness. I've played a few of the available demos now and have another few downloaded that I hope to get to tonight/tomorrow.
Circuit Superstars
Dev: Original Fire Games
Pub: Square Enix
Small demo with just one track, two cars and local multiplayer. What is here though shows great promise. It has a great look and the handling model is simple but with enough depth to make chasing time on the demo surprisingly fun. Definitely one I have added to my wish list and will almost certainly pick it up when it releases in early access.
Raji
Dev: Nodding Head Games
Pub: Super.com
The demo seems to be essentially the tutorial area for the main game. I love the ancient India theme and Raji is beautifully animated. I'm not sure I love the feel of the movement and the combat but it's certainly not bad, I just need to play more I think. I'm going to wishlist it and keep an eye on it in the future.
Unto The End
Dev: 2 Ton Studios
Pub: Big Sugar
Skill based adventure sword fighting game. Feels too weighty for my liking but this will absolutely be someone's jam as I can see some real potential depth here in the combat, getting it right would be very satisfying, I'm just unlikely to ever get it right enough!
Drone Swarm
Dev: stillalive studios
Pub: astragon Entertainment
Great concept with an amusingly ridiculous but nicely presented story that isn't quite as intuitive as I'd hoped to control. I'll be interested to see how it develops in terms of upgrades to your swarm so it's another one I'll keep an eye on.
Mr Prepper
Dev: Rejected Games Sp. z o.o.
Pub: PlayWay S.A.
A very PlayWay game. Could be fun on sale or if this kind of game is just your thing. Muricaville made me chuckle. Added to wishlist but definitely a wait for a sale game for me.
Undying
Dev: Vanimals
Pub: Skystone Games Inc., Vanimals
A survival game with some possibly interesting takes on the genre. I like the art style and the movement and combat whilst simple feel OK. One to keep an eye on for me so wishlisted.
