The games look kinda like Diablo 2 to me

do they all run same engine ??

wait tactics has multiplayer

any way to take that game as the base of the mod and apply it to the first 2 so they have roughly same co-op workings ???

wouldnt mind if its like halo 2 co-op where game doesn't even recognize a second player when comes to story

Actually, there is a fanmade http://www.fonline-reloaded.net/ of Fallout 2. But be warned, players can be hostile, once you are dead, you loose whatever you're carrying.

Any way get a private session like Diablo 2 so can play the game and not be trolled ?

Not that I know of but once you figure out the world it is fun.

mostly my best friend has terrible internet and private co-op games work well enough but once they try log into mmo type games it makes them crash every few minutes or they teleport due to lagg and get flagged as hacking and banned

Well Fallout Tactics has multiplayer mode. I believe you can hook two computers up and play it with just the two of you. Or make it so you can go online and only except who you want to play. Not to many people are playing it online these days.

Tactics online is a long the lines of King of the Hill can Capture the Flag online. So basically it is pure combat.

i wanted a full game with them like diablo but fallout lore x.x

how hard would it be to crap a mod together that takes fallout tactics multiplayerness and applies it to fallout 1 ?
