Infernal Machine was the last truly great Indy game - and, unfortunately, it may remain one, since the new title looks as if it will have nothing adventurous in it and will instead be even more arcadish and consolish than the already soulless enough Emperor's Tomb. Sadly, it looks like this is what's going to permanently replace the best elements of the best Indy games - instead of exploration, there will be going forward and beating up everything around; instead of adventure - a "Can you click the mouse quick enough to do a triple-jump?" kind of problem.
Four quick notes - keep an open instance of M$ MediaPlayer to have IM run under Windows XP; try first if you can play it in its default version, without the patch applied, since it introduces more problems than it fixes; in cases of problems with "frozen" screens or characters, open and close the game's advanced graphics settings; if stuck, type "fixme" from the console...
