Who created the best Amiga games?

After Amiga years, yes, but what about before?

They developed and published many games, as well as publishing many for other people. Some they developed themselves include Stryx, Microcosm, Nitro, Novastorm, Obliterator, and they co-developed quite a few such as Shadow of the Beast, which was between them and Ubisoft Reflections.

And even Lemmings was actually co-developed between them and Rockstar North.

Yup, but possible the best Psygnosis games were done, not by Psygnosis itself, but by DMA Design or Reflections.

True. Reflections and DMA did produce some great games. For Psygnosis I think we can both agree that when we used to see a game with their name on you could pretty much guarantee it would be worth playing and a polished release.

I thought the same exactly. :)

Titus :p (run and hide before being kill with fire)

Oh, they did have some good game releases among their rubbish.

My favourite was the puzzle game Titan. I played that for a long time before actually beating the game, and it was hard.

And their mascot game "Titus the Fox" was a pretty decent platformer on the Amiga, although I understand it wasn't so great on some other platforms such as the Game boy.

Definitely not the best developer by any means, but some good stuff.

There was also a top down multi-directional shooter called Battlestorm which was obviously based on Xevious and a few other arcade shooters with the multi-directional movement, and even the graphic styling, but it was still quite good.
