Here’s all the reviews I could find for Blackthorne. Just the 2 this month and the one mag I have a near complete run of, PC Zone, didn’t bother reviewing it at all which would at least explain why I didn’t hear about the game at the time. Not that either of these reviews would have made me likely to buy it.
You are probably right. It’s a plus point for me to be able to play another game like Flashback/Prince Of Persia these days. I would say it’s fair criticism that Blackthorne isn’t necessarily better than any of the games it is copying. £40 does seem a bit steep looking at it now given all of those would have been budget titles by then.
