Aside from the original Metal Gear for the NES - a game I remember mostly as a series of frustrations - the only other Metal Gear game I have played is Metal Gear Solid 4 - Guns of the Patriots. It was one of the first games I played once I had a PS3, and I remember reading glowing reviews of it beforehand. While I liked the game, I never loved it.
It IS fun in parts, but in others I was left kind of bored. The stealth is good, the weapons and gadgets are cool, but it also has idiosyncracies that had me scratching my head. First of all, I don't mind long cut scenes in games (I love Xenosaga), but the ones in MGS4 were pretty tedious sometimes, and I imagine not just because I didn't play the other MGS games. Repeated long shots of frying eggs is what I remember most.
There are some really fun parts in this game though, and some cool boss battles. However, I remember one level where you have to track someone down in Berlin or some other succh European city using this radio scanner and I HATED that level.
Still, like I said, I enjoyed playing this game. I guess I just never got into the whole MGS thing. I would like to play 5 though.
Not even Twin Snakes? Geez, Matt.
MGS 4 is a pile of overconvoluted crap.
You know, I got a PS2 late, and I wasn't gaming much then, so I missed a lot of games.
You never got a Gamecube?
I did but I got that late too and only had a few games.
I think the first 3 are the way to go. I really liked 2, despite all the criticism. People like V, but that's such a departure that I'm not sure I'd like it.
I really want to try 5
My friend rented the NES Metal Gear games a couple of times. The stealth gameplay was new at the time, but not my cup of tea. I did get Metal Gear Solid 3 when it went down in price on the PS2, though. Why? Because it had an Ape Escape mini game in it!
I tried to play Metal Gear but it just wasn't my thing. I'm pretty sure my younger brother beat it though. He really got into it.
I never played it because I always shy away from stealth games. I get really impatient and frustrated with them, generally.
Most of the time, I do too. But I liked Splinter Cell.
I had Chaos Theory one time. I don't think I got around to playing it though. I'd give it a shot if I could play it on current consoles again.
As a huge Metal Gear fan, I loved how MGS4 tied the whole series together. And the suprise appearance at the end was amazing; this game also turned Raiden into a badass. MGS5 I absolutely loved, and you can pick up the entire “complete” edition for $20 I bet. MGS5 has the best gameplay in the series, the story is very light though. I definitely think it’s worth a playthrough.
