We've all seen games built for coop, like Resident Evil 5, or traditional games where coop works well too, like the Halo games. But I've never played a game that is so dedicated to being a great coop experience as Lara Croft and the Guardian of Light is. It's not two almost identical characters doing almost the same things, like in RE5, where the difference between the player characters is almost non-existant.
But in LCtGoL, you have two very distinct characters with unique abilities that work well on their own, but can be used in totally different ways by opposite character, which brings the interaction between the two players to a whole new level. You play as either Lara or Totec. Totec can throw spears, and Lara can climb onto those spears to reach higher ground. Lara has a grappling hook, and Totec can balance on the string or be tethered to Lara, so he or Lara can rapel down walls that couldn't normally be reached. And there are even more elements than that.
All of that wouldn't be for much if these elements weren't used well, but the game has lots of excellent usage for it all, both in exploring the environment and solving all the game's puzzles.
I really, really want to see where Crystal Dynamics take the game from here, because they something really great on their hands.
Does anyone know if there are any games that are sort of similar to it? I played through with my girlfriend, and I really want other games like it, because we both had a great time playing through this.
