I don't know how people don't fucking love this game. I haven't been blown away by a game since my first playthrough of System Shock 2 in 2008. That said, hearing how people are abusing Blink makes me think that a lot of people are just ruining it for themselves.
So I'm just going to keep messing around, soaking up the atmosphere, playing whatever strikes my whimsy from moment to moment, reading all the lore, and solving all the puzzles of how to get from X to Y while killing or rendering Z useless, and I'm going to keep having
fun. You optimalist players keep on ruining the fun for yourselves, I guess.
You can beat System Shock 2 on the hardest difficulties by smacking things around with an upgraded wrench for basically the whole game; it in fact becomes the most efficient way to play through it, and by the time the wrench starts to be less powerful in late game, you have access to the juggernaut that is the assault rifle. Like Blink-only runs here, wrench-only runs in SS2 are a common thing as both are powerful enough to rely on getting through the game with.
Rigid effectiveness should matter only up to a point. In all of these 'emergent'-style games, it becomes largely up to you to mix things up and create your own fun; there is always going to be an optimal way to play through it if all you care about is beating the game. I view Blink as a synergistic tool to create combinations with the other abilities you have at your disposal, and I experiment with play styles and combat encounters. That is the draw of these games to me.
I did not know you could do that in System Shock 2, and I have been better off for it. So much of the game's appeal comes from the moments of manic tension where you're scrambling for ammo while listening to enemies hunt you down.
I can't imagine playing in a min-max way that rigidly adheres to some method of ideal game completion. The very concept is repulsive to me.
