And yet some people will not bother one iota about a failure of the set if they are particularly enamoured with the performance of the cast. Or the demo tape of a band who couldn't afford to have it produced properly, some will enjoy the music that much that the low productions values will be insignificant. Or pretty much any time you go and watch a band live, the quality of the music and singing is not a patch on the quality you get from a well produced studio recording, however, that doesn't matter because the live aspect of it enjoyed with a group of other fans more than makes up for the lack of quality in the music.
And that's how I feel about PC2, yes there are some issues, some bother me, some don't but the overall experience of playing the game is, for me, second to none when it comes to the representation of motorcar racing. It's got soul, you can tell the team that put it together have a great deal of passion for motorsport.
And in all those instances it comes down to your subject experience, if that subjective experience is good enough, some people will not be affected by the objective difficulties.
GTS is a perfect example, looking at it objectively it a very polished well put together game with very little to pick fault with. However, subjectively, sat in my rig steering wheel in hand it's not a patch on what I feel or experience when I play PC2.
'bout 5 1/2 hrs. until start.
