I like to explore to the end of the map, but how games deal with the practical necessity that you can't go any further is variable.
I don't mind:
- Plot barriers, such as the fatal radiation along the western side of the DC wasteland
- Physical barriers, such as mountains or seas
I'm less taken by:
- 'You can't go that way' invisible walls.
I dislike:
- Invisible walls within the map - the central hills in FNV should have been navigable if you really wanted to.
How do you approach map boundaries and invisible walls (and have you been somewhere you shouldn't be) ?
Boston is not an island or a mountain valley so will it just be 'don't go further' messages?

. However it wouldn't end the game anyway. In early demos the Mad Max people said that if you run out of fuel they will spawn gas nearby to not make it too frustrating. That spawning might not happen in the off-map void. However in more recent demos they said your car will just move slowly.
