I own GT2 and 3. I've played GT3 a lot (a few times but never past like 50-60% before). I've played GT2 some, but not too much (I'd say maybe 10% of the entire game). What are your opinions on purchasing the original? Is it worth it... considering it's only $15? Is there enough unique gameplay separate from GT2 and 3 to merit buying it? Are the graphics, sounds, and controls too antiquated to go backwards in the series that far? Just asking opinions. Thanks for your time.
