I finally got around to The Darkness about a week ago and really enjoyed it. The game has a ton of stuff you don't see everyday like weird phone calls you have to make for bonus content, occasional messages received via a pager, and an open world like structure that has you taking on optional side quests by revisiting areas by subway. And man, having lived in NYC for 5 years, the subway stations are so lovingly rendered, it made me miss a part of my life which I don't remember really that fondly.
Anyway, those were all well and good but the thing that still impressed me wholeheartedly in 2017 was the voice acting. Across the board, except for the kids, just do a fantastic job with lines that aren't necessarily all great. There are stuff about this game that don't hold up today and probably weren't great even then, like the the shooting, but I can definitely recommend it. The problem is, it's only on PS3/360. I was able to cop it for $5 at a local game shop so I doubt it'll cost you an arm and a leg but you will have to drag out your old system.
Which games still impress you to this day and why? (This isn't a thread about whether a game holds up. I'm asking what aspect of an older game impresses you today.)
Please, pick a game or 2 and explain what's impressive to you about them. Lists are boring.
