Answers to my own questions: (Based on looking at the Steam images and the RMWeb Store images) For the RPG Maker DS packs for MV the tiles are mostly the same as FES, but manually up-scaled to be 1:1 in MV. In the first pack the characters are different from the FES ones, in the second pack it seems like the characters are the same as in the FES Sci-Fi/Modern and Sengoku DLCs. Unfortunately it doesn't seem the DS packs will work with FES even though they technically include(most of) the same tiles(the characters, enemies,). DS assets have been more manually up-scaled so the pixel count on each sprite is 1:1, with FES all the pixels have been enlarged 2x to fit in MV. See #1 These packs are still amazing and the fact that they've been up-scaled for MV means that people might be able to use them with MV RTP graphics is great. Although there are small differences between FES and DS I am loving the FES stuff so here's hoping you guys will release the FES DLC into a pack for MV like the FES RTP!
