its a decent game in its own right...
but the basic transposition of Half Life onto mars is rather frustrating for anyone seeking originality..
the graphics are pretty decent and the lighting effects are great... I reckon the graphics are better in far cry (and more spread out/larger maps... better story and stuff) but doom3 in its own right is not too bad...
the game could have done with far less bogus repetitive levels that add nothing to the story...
look @ halo... everything progressed to a point and beyond because of the storyline... doom3 doesn't have that unfortunately
the AI is also unfortunately inferior to some other games BUT the sheer quantity and speed of the NPC's is challenging at times
the chainsaw is a lovely addition
the pda == a deus ex ripoff basically but not quite as useful... its a cumbersome tool specially when trying to get numbers for lockers... in deus ex at least all pertinent data when you picked something up or explored was saved separately and you could look up all the numbers w/o having to check the whole thing... coulda saved some time...
in general I guess I would give the game between a 3/5 and a 3.5/5 OSNN star rating..
its a decent product but just doesn't live up to the hype and the lack of originality is a glaring flaw...
