Is there really a point to getting DR2 and DR2 OTR? Isn't OTR the same as DR2 but with a bunch of extras?
You play as a different character and the story is different as a result. That's pretty much it as far as I know (though feel free to correct me anyone). From what I've read, OTR is the superior game.
They're different games with different story lines. I liked OTR better, as it doesn't have the time restrictions that DR2 had. Both are pretty solid though.
First, there are still time limits on the missions, and if you miss the key missions, you still fail the game and have to reload. It happened to me and a friend several times. jshackles might be referring to the fact that there is no overall 72-hour time limit, but that was really more of an end-game timer because if you didn't do the key missions within their specified timeframes in DR2, you still failed the game and the overall time limit didn't matter. I can't confirm or deny that DR2 OTR doesn't have the 72-hour time limit, though, as I don't remember.
Second, I played the SHIT out of DR2, and went into OTR hoping the story would be different. I am about a third of the way through and the story is basically identical to DR2, with even the exact same cutscene dialogue from characters who are not Chuck/Frank. So far, I have done the same things, fought the same bosses, in the same order as DR2. They are even in the same fuckin places (survivors who must be rescued are in the same places as well). I was really disappointed by that.
I liked DR2 better, at least so far, because it felt more insidious than OTR, which has more levity. Not to say that DR2 isn't silly, because it purposefully is, but it is also a very violent game with some seriously evil bastards in it. OTR feels a lot more like a romp, and tonally I just preferred DR2.
