It’s really a simple downscale from 1080 to 720....which isn’t really a big deal...
I'm not going to go quite that far. I know from experience that just shifting something over like that isn't always a matter of flipping a variable in the code. Sometimes it can require a significant amount of work, especially if the original game was created with one specific render target in mind.
The thing is, most games these days aren't developed with one render target in mind. In fact, it's quite rare for a game to be developed with one platform in mind, let alone render targets. For several years now, creating games in a more scalable manner in order to get them on multiple platforms with a myriad of different technical specs has been the standard, not the exception. And this is part of the reason why we are seeing down-scaled ports coming to the Switch. For a game designed with scalability in mind, a down-scaled port is easier and less time intensive. A lot of the graphical assets may already be designed for scalability, which makes the process even less difficult.
Since this trend is likely to continue into 2018, it's time to start taking bets on which older title is going to get a Switch port next. What game from about four or five years ago would be the best fit for the platform? Which would scale the best? Which would address a lesser-exploited demographic?
My personal pick is... Alien: Isolation. This is a bit of wishful thinking on my part, I'm a huge Aliens fan. At the same time, it does meet a lot of the criteria. It's reasonably scalable, the original release came out on PS3 and Xbox 360 alongside the PC and PS4/XBone ports. It caters to an under-exploited demographic on the Switch, there aren't a lot of horror games on the platform yet. It's a game that sold decently, but not spectacularly when it originally came out, so Sega might very well be interested in squeezing some more money out of it. And it got a decent amount of critical praise, making it less risky. An Alien: Isolation port release in time for the Halloween season 2018 would be fantastic.
