"Played the alpha a bit, really enjoyed it. I'd compare the gameplay to CS:GO, except with reconnaissance, rappelling, and fortifications. But for me, the big draw is the end-of-round respawn. A hugely under-appreciated mechanic if ever there was one.
The continuous respawn you see in games like CoD or Battlefield might keep you in-game more often, but you never get those tense moments where you're the last player making a heroic last stand against the surviving enemy team. You never regret rushing out and dying immediately either, since you'll just return in a moment. Your life has no value when death is only a minor inconvenience: a few seconds wait until you're back up, running and gunning.
But in Siege, as in Counterstrike, every death matters. Every kill matters. That gives the moment-to-moment gameplay real weight where most other multiplayer FPS games are just an endless cycle of kill/die/respawn, grinding your way toward a positive K/D ratio through innumerable, inconsequential deaths."
Couldn't agree more, that's why I don't like team deathmatch much.
