The game I've been working on in RPGMVX, I don't have much to show yet, but here's the premise (and I believe the concept has been thought of before.. but whatever)
This isn't a sequel, or remake, it's a re-imagining. Instead of re-making all 4 PS games, I've decided to re-write the storylines of all the games slightly so that they all play out within the time span of a single lifetime. The game will feature almost all of the characters from all 4 games in some form or another. You will begin on Palma, as Alis, then after defeating Dark Falz, will timeskip to Mota (in the game Mota is split between the Biosphere, PS2's mota. and the Wild Lands, PS1 and 4 Mota. Towns that are duplicated will be replaced with new ones) and you will play as Rolf, after this storyline (and during actually) the play will skip ahead to Alisa III (I've made this an experimental biosphere created by Mother Brain and isolated from the other planets)
Eventually, you'll time skip again to Chaz, and his quest. Characters you have previously met will age throughout the game, and it will be possible to unlock 'secret' party members, including aged versions of previous party members.
At present, I'm using the default VX tileset to map the worlds (I'll probably end up changing it later and remapping them with PSG1+2 tiles.. but that's collosally hard work) and PSG1+2 sprites and battle graphics. The music will be a mixture of tracks from the different games. I'm especially looking forward to re-imagining the Alisa III section of the game.
I've so far added in most monsters, using PS2+4 sprites for the moment, starting to actually script soon. The battle system is for the most part done as well as I can with limited scripting expertise, there's also a minimap scripted in. Here's a couple of preliminary battle shots. Yes, Nero has replaced Myau, he won't die at the start of the game this time
