You're like a guy in a wheelchair who is shocked to find out that people classify him as a cripple because he can't get up a set of stairs with out the help of others.
I've played and completed many of your late-90s so-called classics and found them wanting in many areas. I've also played and completed some of the early-90s so-called classics and came to similar conclusions.
So your gimmick is being the guy who hates challenge in video games and buries old classics on a forum that is almost dedicated to praising old classics and burying modern pussified games. Like I concluded earlier, you're an enemy of the CRPG genre.
Also: I never said that all 90s classics are flawless. Just that there aren't major design flaws in Nocturne and Dark Souls as they get everything right from story (+C&C), atmosphere and art direction to mechanics, gameplay, difficulty, level and encounter design where as something like Arcanum, Morrowind, New Vegas or VTMB is flawed despite the fact that they might do some things really well and even be brilliant at times.
They could have made the game on a better engine, like how Obsidian chose Gamebryo for New Vegas.
Because game developers have limitless budgets, manpower etc. Especially ones who make niche games that don't sell very well.
To quote SS2-guy: Nah. When it comes to lazy-storytelling like audio logs everywhere or a cool antagonist who makes fun of you periodically, SS already did it. It has well-designed levels on the Von Braun and that's it.
Never mind the ideological battle between the two different antagonists and the storyline which was ripped to Bioshock where it was considered to be so good that less intelligent/educated gamers regard it as one of the best examples of the artistic merits of the medium.
On top of that it was the first game to properly combine FPS with RPG, at least that I know of (*). Created the basis for Deus Ex along with Thief (and maybe Half Life) and on top of that influenced Doom 3 (the biggest FPS series of the time completely changed its design philosophy just to rip it off) and Dead Space (and to lesser extent many other games).
*=There's strife but I've never got around of playing it so if it has as much depth in its RPG systems as SS2 and firearms then correct me if I'm wrong.
By the way, System Shock 2 bombed. Bloodlines also bombed. Other so-called classics from the same time period did not bomb, and this is because they actually had decent-enough gameplay to offer, unlike those titles.
You're using sales figures as an argument. On RPGcodex?
Stating that a game didn't sell well because it lacked good gameplay is retarded because it doesn't apply to RPGs nor other genres, back then nor now (though it's more common these days). Plenty of examples from that era (+- 3 years). ToEE, JA2, Wiz8 vs Diablo 2 and Morrowind. Shin Megami Tensei&Tactics Ogre vs Final Fantasy, Grandia and other popular JRPGs at the time. Toonstruck vs Phantasmagoria. Klonoa: Door to Phantomile and even Castlevania: Symphony of the Night vs sluggish 3D platformers. Blood vs Quake 2/Metal Slug vs Turok (can't think of a poor 2D/needlesly 2.5D run n gun from that time, the PS1 contra games were bad but they didn't sell very well either). Mortal Kombat (+Rise of the robots) and later on Tekken/Soul Calibur vs all the innovative and much deeper and better looking fighters on Neo Geo/Saturn/Dreamcast. Outcast and Beyond good and evil vs most 3D action adventure games. I think there were couple of bad polygon shmups on the PS1 that sold better than games by Cave, Treasure and Raizing. Almost anything 2D back when 3D was all the rage. In fact you could argue contrary to what I stated earlier and say that back then it was easier for well designed games with good gameplay to get lost in the shuffle because consumers were so enamored with 3D. Or at least marketing people and publishers kept showing it down peoples throats and people kept buying it.
