They, as in Psygnosis, completely milked the Lemmings IP over the years. The 3d episodes were pretty bad and that was the end of it if I recall correctly.
Lemmings Revolution was particularly silly as it's basically the 2D game but superimposed onto a 3D cylinder. Luckily games have moved away in recent years from the "everything must be 3D just because" era of the late 90s.
Back in the amiga days I loved a somewhat similar one called humans. It does seem weird that such a successful game hasn't spawned more clones though.
