To be fair chemical_art, trailers were done VERY differently back in the day:

And yes, FTL got away with marketing itself without mentioning another game BUT, as far as I'm concerned, it's so completely unlike any other game (I've heard of at least), that it would have done itself an injustice to compare itself to another game.
Another TBS that came out recently was XCom: Enemy Unknown. It was made by a different developer, and is a completely different game than the original (only moderate similarities), yet it sold itself as a sequel to those and did fantastically. Fallout 3 had almost NOTHING in common with Fallout 1 and 2. Fallout 1 and 2 were top-down TBS games, Fallout 3 was a sandbox FPS/RPG game.
To say that alluding to old, nostalgic games that people loved does not help sales is insanity, especially if those games are part of the structure which you're basing yours on. I would personally be pretty upset with Arcen if they did made an Oregon Trail-like game, and didn't somehow include that in their trailer. That would seem like a huge rip-off to me.
I agree with you. I don't particularly have fond memories of Oregon Trail, I always thought it was kind of a stupid game. But I remember as a kid that EVERYONE ELSE did, and that's what's important. Hell I know people who didn't like MARIO. Should Nintendo stop making sequels because there's a few outspoken people who never liked it?
So what I'm saying is that I don't think it's a mistake to mention old, nostalgic games as your marketing ploy. Yes, it needs to be games that people actually liked, but I think you've got a huge potential playerbase for Oregon Trail "sequels".
