Not sure what you mean by logistic...
Unlike Earthbound, the game is open world for the most part, i.e. you can go anywhere, and no one tells you to go anywhere nor are you forced to. The only exception is the beginning of the game. In that respect it's sort of like a more RPG-ish version of Zelda I, as there are towns and NPCs(just like EB). The "humor" of EB is, while present, not as prevalent in the game. I mean, you still phone your dad to save and whatnot, but you won't be seeing characters like the Runaway Five or Mayor Monotoli, and even the NPC's aren't too memorable. It's more of an adventurous, quiet and somber-type of game in comparison, and overall the feeling it generates on you is much more subtle. For example, while EB may have a lot of build up towards you getting a new character in your party, EB Beginnings just throws them at you unexpectedly, you just meet them in your travels on the way, so in that respect it feels more fluid and a part of the game world rather than the game world orchestrating you to go and befriend a particular character. This is one aspect I really liked of the game, the quietness of it.
The game also has a lot, and I mean lots, of dead ends in its overworld, and there's a lot of space that may seem unnecessary, and these just muddle you up with random battles. Oh yeah, the battle system is typical of any NES RPG, so if you're used to EB's innovative one, then well you'll have to go back...your item space is also much less than EB, your attacks are worse, the enemies are harder, there's very little you can do if one of your characters is dead(remember that bit about dead ends and open worlds? Yeah, it's not really a good thing for your party when your only chances of reviving are hospitals in towns which, if you can even get there without getting lost, have even more random battles on the way)...just like a standard NES RPG basically
These all sound like really bad changes if you're used to how EB dealt with them. But if you view it as just another NES RPG, the game's structure is actually realistic(in a good way), you actually feel like you're a little boy in danger as aliens are attacking, and every event in the game feels like it happens more because of you than the game trying to set you up on a path, so in that sense the whole world of EB Beginnings just feels...alive. I played Beginnings first from the Mother trilogy, and it is easily my favorite of the 3. Transitioning from Beginnings to EB is easier, the changes are more than welcome, it's regressing back from EB to Beginnings that I imagine will be problematic.
