I need to figure out a computer I can get or a solution to my problem?

I would like to start off by saying I have a 1T external drive, and I downloaded Sims 3 to it but when I click it it re spawns it on my computers drive. Is this because if the computer I have or because it is a laptop? I hear people saying they play it off the external drive so how? I want sims3, sims4, Minecraft, and probably dome other things like Garry's mod and roblox. I will want a lot of expansions and cc for these game. So I want to use my external dive but it keeps respawning. I want them all on it at the same time also. I'm looking at just getting anew computer. Can someone tell me what is the best computer (preferably laptop) that will leave all these on my external drive. I want as cheep as possible that will do this. Please answer from knowing your laptop or computer runs some of these games off the external dive only or if you know someone who does.

So, some applications can be installed and run completely on an external hard drive or thumbdrive. Most are things like small utilities like an anti-virus or anti-malware scanner. This way you can just plug the drive into the affected computer and run them without having download/install.

But most applications and games install system files (DLL libraries) and those have to go into the Windows directory on your primary hard drive. So you can't have a portable installation of The Sims 4 on your external drive that would work on any computer you connected it to.
