Just beat MGR.
Well, what to say? It was one hell of a ride. Good combat system (my only dislike is the parry), especially loved Blade Mode, nice story, awesomely shot and directed cutscenes, cool action visuals. I loved it and I want more. Yep, officially an MGR fan now.
Good thing that MGR is an action game I suppose. I've never had the chance to play the MGS games, but from what I've heard there's a lot of cutscenes, almost Quantic Dream style, and they're stealth games, a genre I'm not particularly fond in, if it's not Splinter Cell.
But I'm curious to know more stuff about the Metal Gear universe, I might play the older MGS games on an emulator.
Also, I might be wrong, but seems to me that Raiden is disliked by a lot of people. I can't understand why, I liked him. Maybe it's because of how he is in MGS2, maybe he's different there? I don't know, but in MGR, he seemed to me a solid action character, fitting the tone of the game.
So yeah, it was fun and challenging (except Sundowner boss fight, I found that very easy... Jestream Sam too), I look forward to an hypothetical sequel (I've heard rumors that it was teased).
