I have been using RPGMVXA since it was released in japan and love everything about it. Welcome to the Ace world.
On your Parallax mapping question I would suggest that you do more research into what other features you want in your project as some of the overlay mapping, tints, fogs, and many other options are not compatible with all the parallax scripts but I would recommend a few
YEA -Parallax lock by Yanfly This gives you the option to lock your parallax from moving with the use of a notetag in the notebox of the map. Keeps it from Scrolling up or down or both. There may be other Parallax lock scripts..but I don't use them.
Fogs and overlays - There are multiple fogs and multiple overlay scripts out there. Do some research and find out what fits your needs best.
(added) lighting - if you use additional lighting script it can result in some nice effects but if you add to much or use large maps it can lag you game down fast.
ODM = Wish I knew what you meant by ODM and victor engine couldn't pinpoint what you meant pal.
Victor Engine - is good but most of the battle and other scripts are very complex and requires a lot of customization, setup, and can be a frustrating pain in the rear. So I would not recommend it for beginning RPGMVXA users unless you have a lot of time to sink into learning the whole system.
There you go NovaMondo (Cool username btw) any more questions I will be around.
ODM_ DONT DOWNLOAD THAT CRAP!!
