Harry Potter Gets Azkaban Game, Stone Brickbats
Thanks to TotalVideoGames for its article revealing EA's announcement of the Harry Potter and the Prisoner Of Azkaban game adaptation, due some time in 2004 and giving fans "the first chance to play as friends Ron Weasley, Hermione Granger, along with Harry Potter, switching between characters and utilising their key attributes and skills to resolve challenges." An interview with the game's producer over at IGN Cube further reveals players "will also get the opportunity to control Hedwig and to fly Buckbeak, the Hippogriff", and this internally-developed EA title will hopefully work better than the recent Warthog-developed Sorceror's Stone adaptation, of which 1UP commented it was "a mystery why anyone would want such an imaginative world filtered through trappings as bad as these", and IGN PS2 lamented was "strangely nowhere as compelling or refined as Chamber of Secrets."
...reminds me of the old Day of the Tentacle game where you could swap between characters as the game progressed. I'll assume that the only difference between Maniac Mansion/DotT will be that they were great and the Potter games...well...will suck for sute :(
Are there any good ones, for PC or otherwise?
People seemed to like GoldenEye for the N64.
Goldeneye for the Nintendo 64 was probably the best game ever published for that system.
Star Wars: Knights of the Old Republic is a very good RPG based in the Star Wars universe (but not on any specific movie.)
Star Trek Voyager: Elite Force (and Elite Force II) are very well-done Star Trek games. (TV, not movies, close enough.) They even had the cast of the show do the voices.
So yes, they do exist.
Comment of the year
They're relatively simple RPGs, but they are RPGs. Leveling up, item collecting, fighting battles against random rats...it's all there.
I know that's not quite what you want, but it's your best option as of now.
Goo goo g'joob.
