The reason the music has changed is this is now ZP2: Escapist Within. Like all good sequels, the darker and edgier feel has been matched with MOAR HEAVY GUITARS.*
I'm also very disappointed that no-one has made a "Oh my god, Yahtzee so only reviewed this game to piss off the Harrison Ford fans. It's like he wants to alienate EVERYONE". For shame, sensationalising forum-goers. For shame.
As for the actual review, I more or less agree - it's not perfect, but fun is something somehow deeply ingrained into the source code, despite not showing up sometimes.
Like schizophrenia.
*For those lacking a sense of humour, I am joking. There was a charm to the old intros, no-one can concede, and the new one looks more than a little... flash (not necessarily bad or wrong, but definately a "What the fuck?" moment) and the music didn't quite fit perfectly (again, not necessarily bad, just not - in my opinion - entirely fitting with the feel of ZP).
LE EDIT: Oooh, forgot to finish my train of though. Continuing on from the previous paragraph, replacing the full stop with a comma:
...but charm gets it's arse sued off of it by Copyright Infringement Law. Alas.
