I've been working on this pet project for a while.
In order to see this free MMMerge Chart, Just access the link below.
Feel free to make a copy of this original version for yourself, so you can use it for games, or even make structural changes to the Chart.
Chart as Google X-Sheet:

And here is a partial screenshot of the MMMerge Chart:

At the time of this first post, the Chart is certainly not 100% achieved for MMMerge --although it is covering most of the more relevant features of the combined games.
Notably, Verdant's Quests are still missing, but the majority of the games' Quests are present and well organized.
Major details about the game progression are secured already: such as Obelisks, Arcomage, Challenges, Altars, Fountains, Wells, Water Pools, Alchemy Recipes, Travelling Schedules, Map Visits/Visit Dates/Map Reset, Items' Tiers; but minor details, such as Points of Interests, Chests and plenty of other secrets are just missing (especially in Dungeon Maps).
I know there are unlimited ways to make Charts for the games --and in this case, it's a virtual Chart on Google X-Sheet: it has pros and cons.
If anyone is interested in improving or collaborating in this generic Chart making for MMMerge, feel free to share your experience, provide critique and suggestions for this Chart. I'll be glad to discuss any possibility of improving this stuff.
