Two vanishing points won't help *as a rule* but can be part of the solution. The thing is that, as Monsiour OUXX said, you're dealing with a 2D image in which a character moves in a 3D way. But fortunately a long history of games is already working for you: Players are usually aware that adventure games tend to cheat a lot. For example, virtually every classic adventure game displays its characters as "front views" when in reality they should be tilted a little. And scaling never looks totally convincing anyway.
But the larger and more complex your environment, the more players will notice that there is no true 3D.
Some "rules of thumb":
- a very low horizon line tends to create scenes that look "flat" but make it easy to have a character move around without ever looking too weird
- in a scene with much depth, restrict the area your character can actually walk around in.
- try to design the "main area" of a location, where all the cool stuff happens, to have no scaling at all.
I need to add that I am no great fan of perfectly constructed perspective anyways; a little creative cheating can make a scene look actually better than the "realistic" one. It's a game and people are aware they are playing a game. That may sound lazy but... how often do you feel better after eating a health kit?
