There's "impressive", and then there's "fun". The later is what stands the test of time, not the former.
True, but we are looking at it from 2 different perspectives here.
Mine is quite simple.
I'd enjoyed the game immensely at the time on the ST , so was delighted to see it coming to the Sega formats i had moved onto...having paid £270 on day 1 for the Mega CD, i was understandably praying for games you just couldn't do on the bog standard MD hardware..sound and intro aside, Prince Of Persia just didn't deliver anything like what i had hoped for, so it didn't get the playtime the Game Gear version did.
Maybe my expectations were set too high?, but having spent so much money on an add on, i think they were justified.
I gave it one last shot on the Sega formats via Domark's cartridge version as just found they'd gotten more from the hardware.
By the time it was released however, the benchmark for MD hardware had moved on and titles like Flashback made Prince Of Persia seem dated.
I never tried P.O.P 3D as it was annouced on Dreamcast but i never saw a UK release so not sure if it made it at all...
I did try the PS2 reboot of the franchise and whilst technically impressive, i hated it.
