when purchasing a game is there a time limit or is it ongoing?

Answer 1

if you mean downloaded a game
i can only answer this through the expeirience i have with downloading a game and on my mobile phone i can either pay 50p-£1.50p for 24hrs play
or pay £5-£6.00p for the licence to "own" the game for ever
owning means you have to read all the end user licence agreement crap first
and either agree or disagree with the rules and regulations first,if you disagree you cant have it at all,so the end user licence agreement should just have" I agree "at the end of it
and a cancel button.

Answer 2

Huh? Could you possibly be a bit less vague.
