10/10 - Agree Disagree

I consider myself a DX hardcore veteran and this is pretty much the perfect re-imagining of the clasic DX, down to cheezy (sorry!) voiceacting and story choices that prove meaningless in the end. But Nihilum also menages to capture all that was great in the first DX - with emphasis on exploration, fleshed-out world (with far less flavour texst than DX, but still a bunch), paranoia and making any style of gameplay valid. It is not a perfect game though - it carries all flaws of the original DeusEx - dumb AI or maps allowing players to jump into plains outside proper map limit. for example. But then again - it is a mod and when evaluated as such it turns out to be pure GOLD!
Deus Ex: Nihilum is slightly shorter than the game it is based, 'only' around hours 10-15 for a carefull, stealth focused and pacifistic playthrough on realistic mode and around 7-10 hours if one prefer run'n'gun on easy mode. It is worth noticing that this is, both in quality and lenght, more than average 60$ new Bioshock clone.
About the run'n'gun aproach - there are few new guns, like M249 light machinegun, P99 pistol, new small machine gun and Gauss Gun, emmiting EMP shots. The last one is a game changer, much like EMP pistol from The Nameless Mod, capable of (almost) silent elimination of bots and messing up cameras. Ammo is also not so scarce like in DX.
Story presented in Nihilum is interesting, gripping at moments, characters are well rounded up despite far from perfect voiceacting (Number's One voice is by far the worst IMHO, but even his lines highlit his character traits, esspecialy in the last act of the game). All of characters act and react to player in logical manner consistent with their own agendas so they all feel life-like. There are four endings, one for each of three faction fighting with two others plus 'sod off' ending. Any ending can be chosen in the very last mission in the game (just like in Deus Ex).
Damn 2k char limit. Just do yourself a favor and play DX:N.
