A fairly solid adventure game bogged down by badly ported controls and an innovative but mostly annoying action system
Pros:
Indigo prophecy is compelling and does suck you in, which is a vital element of any adventure game. The graphics and sound are passable and you feel that you actions are having a direct effect on the plot. It feels a lot like Dreamfall in many ways, and I've you ever played Dreamfall you'll see that's a compliment, in a similar way to dreamfall you roleplay the major characters of the story and the game has cinematic qualities. Apparently the influence that your actions have on the plot can lead to different endings, having only played the game though once I can't really do the game justice on this account so bear that in mind.
Cons:
Indigo prophecy has lots of flaws and failings that stop it from really living up to the standard of DreamFall. First and formost for PC players is the badly ported controls, I played the game with a dual axis controller but certain sequences forced me to switch the control to mouse and keyboard - notably any instance of climbing, as the game failed to recongnise the full range of the controller sticks, making the semi circle motions almost impossible to pull off with my controller. Also there is a significant bug in one of the scenes, with the helicopter where you have to try and hold on - this is impossible without turning the screen resolution down to minimum otherwise a momentary screen freeze causes you to fall.
Bugs and glitches aside, Indigo prophecy bravely implements an action system into the gameplay which is more advanced and more central than any I've seem before, requiring you to copy elaborate sequences with your dual axis pad to choreograph the action sequences - unfortunately this can be a little frustrating and a more fundamental issue is that it actually takes your focus away from what's happening in the game - you're too busy frantically copying indicated stick motions that you don't have time to watch the actual action unfold.
The graphics in Indigo prophecy are adequate but not really up to today's standard, the game doesn't support widescreen and the graphics themselves look almost like a souped-up version of directx 8, having said that it is fully 3d and that's more than many adventure games can boast.
The plot is absorbing but falls into the trap of conspiracy theory cliché which has been done to death at this point and then seems rushed at the end. To be frank I was left with a feeling that I could of done better... a truly good adventure game should blow you away and leave you with no doubt that such a work of art is way beyond your own capabilities, Indigo prophecy fails to deliver that.
Conclusion:
Despite all its shortcomings Indigo prophecy is a solid game that is well worth its current price. I have little hesitation in recommending it to adventure fans. Make no mistake however, Indigo Prophesy is a cinematic adventure and not a puzzle adventure like Myst, so fans of that style of adventure may feel cheated by the 12 hours or so of gameplay, but if that is what you're looking for then Indigo prophecy is a pretty good example.
