Some cyberpunk recommendations (apart from Shadowrun) so I can hype myself for 2077?
Well, it heavily depends on the genre you would like to try.
Shadowrun Series
Syndicate Series
Satellite Reign
Invisible Inc.
Deus Ex Series
System Shock/Bioshock Series
Anachronox
Hard Reset (dumb FPS with some nice scenery/Music)
Ghost in the Schell Series
Beneath a Steel Sky (free on GoG)
Tex Murphy Series
PS: Didn't try all.
Those are all sound recommendations, but to each his own.
For atmosphere you may turn to adventure games, from classics like
Blade Runner, to newer ones like
Wadjet Eye games, namely
Gemini Rue and
Technobabylon, of which there should be a free demo somewhere. There is also upcoming
Dex, which is described as RPG game by some, but I haven't played that yet.
Beneath a Steel Sky is also quite often mentioned in any top cyberpunk games list, and you can get it for free.
There are some mindless FPS's with visual style that can be described as cyberpunk, like already mentioned
Hard Reset, or the new
Syndicate, some even count
Mirrors Edge among those. There also is
EYE Divine Cybermancy, which is gathering rather positive sentiment from the players, but it looks more like a crossover to grim 40K world
.
Master Reboot and
Remember Me also have nice cyberpunk vibe to it, while being quite different.
There are also very decent FPS/RPG hybrids like
Deus Ex and
System Shock, but you probably played them already (if not, Deus Ex might suit the best from this list). There is an obscure one, called
Utopia City, but I know it only from Let's Plays so cannot really recommend.
There are also some playable (YMMV) tactical "RPGs", like
COPS 2170 and Paradise Cracked, which were developed by same Russian studio - I remember abandoning COPS due to braindead AI and sever bugfest, but I remember it had some nice cyberpunk/dystopian atmosphere. Along that line you can find
Ubik (which was very hard to get, when I searched for it some time ago). Also
Satellite Reign is fairly decent
Syndicate "remake", albeit I have played it very briefly, but it is far from RPG.
Overall your safest bet would be Deus Ex series, especially first and third game.
