Fever_Discordia: Yeah the original Discword was published by 'Teeny Weeny Games', it seems likely that the rights went to Psygnosis from there but who owns the Psygnosis rights these days? They seem to have been divided up between Eidos and Sony - lets hope its Eidos!
kodeen: Ah thanks, that's very helpful. It looks like they're more Sony than anything else, so I'll put that down for now.
Yeah, it looks like Sony have been publishing Lemmings games on the PSP recently so they've definately got that ex-Psygnosis IP, probably got the rest too...
