My main problem with SoA has been their focus on being like every one else, thinking they can chase the same sales goals as EA/Activision/Ubisoft by putting out inferior and same-looking games. They used to deliver the goods from SoJ with offbeat, counter culture, and artistically unique concepts that thrived in being or emulating arcade-style kineticism. Since that only seemed to sell on their own platforms, and not well enough to keep them in the hardware business, they jumped into a busy intersection and can't cross the street without being mauled by a monster truck.
Most of their western-developed, 3rd party games now are things that I'd rather watch as a movie than play as a game. I should want to play a game based on the Alien franchise, but nothing SEGA has done with that license stood out as worth throwing money at (Isolation came close). They always seem like they could be ok, but then release at a time when better games or better things to do with my money appear. IMO, the best thing they published was Spiral Knights, but I wish it weren't online-only and pay-to-actually-see-the-good-stuff.
If the Valkyria Chronicles PC port hadn't happened this year, I'd probably be done with SEGA until another Saturn/Dreamcast port happened. I wouldn't even assume any ports could happen anymore, if not for VC.
