No.
If I'm downloading a game, no guilt because I'm doing it for one of the following reasons:
1: No longer in production/ can't buy it anywhere.
2: Can't afford it at the current price so they wouldn't get my non existent money in any case.
3: Try before buy or not buy (definately justified, refunds aren't always smooth with games, you gotta fight for it and I'm a pacifist)
Yeah, to anyone who has time to be guilty about downloading, congratulations, your life is perhaps easier than mine, I have more important things to worry about. (Condescending I know but that's my 2 pence.)
the best thing about memories is creating them.
you can't push someone towards you.
