I will probably restart the game from scrap. I want to make it with RPG Maker MV because I think that with more time and with MV's features, I can make a better game.
I love RPG Maker 2003 but the problem is that it has become too old for me too. I like the feel of old graphics and I like how the events work. And I totally hate how they ruined the event system in the newer versions... but damn, we are in 2019 and I just can't accept to make a game in a 4:3 resolution >__<"
And the 256colors is probably the biggest limit.
So... I'll finish Theia first, of course, but after the release I think I'm going to work on nec(H)roma.
