lisence keys question

[rjk]

i never thought of this before - and it is probably a very stupid question.

i understand games that work with steam cannot be resold as you activate them to link them to your personal account.

however

can you use games software that has been activated before?

eg. i buy a 'games for windows' game off the bay - can i use it if it is used?


thanks for any advice

anybody know the answer?

just checking
i dont normally buy second hand pc games
all of what you guys mentioned seems too much hassle

perhaps the bay should get rid of used pc games on their listings all together - it is very misleading
