Well, there MIGHT be a new Master of Orion; As has been pointed out, the game as it exists right now is somewhere in the “early access” mess.
I too had heard nothing of it until it popped up in the top of the Steam feed. I’d like to say “Hey, good job Steam, you made me aware of a game that I didn’t already know about and which I might possibly like!” until I realized that it wasn’t in any way a tailored recommendation, and is in fact just the Steam equivalent of a banner ad for everyone.
Also, what’s this about $10? The version I see on Steam wants me to pay fifty bucks to be part of their test crew. Though it includes the previous three games, so I guess that’s something.
Reviews seem… unconvincing at this time, though at least it’s apparently no MOO3. My worry is that it’s going to be another tedious, micromanagey MOO2.
