Man, Sony really screwed Psygnosis over. They had a ton of IP that could've been built upon but Sony got mad at their autonomy (despite knowing that's what they were gonna have when they purchased them in '93) and stripped them down to a simple studio with two games.
Then instead of letting them explore other IP, they just shut them down. Probably a warning sign that acquisitions that larger (or larger) in gaming just do not end up going well, we're already seeing some signs of it with Microsoft now and ABK.
