Game info needed,

[2013]

I have a load of pc games I got from a clearance auction,
I'm not sure if they have been used, I know they are returns (some of them are like brand new but the key codes are missing) non of them are sealed but some have the key code intact.

the reason I got the games lot was dues to wanting 3 of the games and they work fine, Ive been told if I try them the games will be useless.

Can these still be used or sold ?

Depends on when they came out any from the last 3-5 years normally need to be activated on steam/origin/uplay and these if the key has been used will be useless
Other games older should be ok just look on the case to see if it need steam ect
Other then that list the games and we will do our best to help I'll probably have them and be able to look for u

All are newish games, the games ive used work.

So im assuming they work, I just don't want to sell them if they don't work.
