VC4 takes place in the same timeline as the original VC games and NOT the recent Valkyria revolution garbage.
save data from the demo can be imported in the full version when it releases, so you can get a bit of a headstart. Doing so will also net you a bonus accessory.
If you’re wondering about the size, it’s definitely justified by the fact that it’s a very beefy demo, including plenty of content.
