The OP hurt my eyes. Run-on sentences are the real problem here.
You know what? Just for me, slap yo' Language Arts teacher, OP.
On your topic, you limited your question to precisely one viewpoint with an obvious answer. If someone who would not normally buy a game got their hands on a free version, the developers/publishers *might* not be losing anything. Oh hey, you got me to admit that piracy may not cause a developer to lose sales in one very specific and very difficult to definitively qualify for instance! Good for you, have a cookie.
Pirating a game is like stealing things from the candy rack in the supermarket. The supermarket won't go under if a few people do it. You're not hitler for taking a pack of gum. However, stealing the gum is still ethically wrong and the store has a right to expect to be paid for it's merchandise, no matter how small.
If it's free or if it's abandonware, it's not pirating. If you torrent or otherwise download a game that's still being offered at retail so as to avoid having to pay for it, you're an asshat. I've yet to meet a single person who has gone back and paid for a second copy of the game they got for free out of guilt or whatever. I can understand having money troubles. I know that keeping up with releases can be hard sometimes. I know there are at least 4 games coming out in the next 3 weeks that I want to buy but can't. I'm not going to pirate them, and neither should anyone else. I'm not saying you/they can't, just that you/they really shouldn't.
I think that there are two kinds of piracy, and one of them doesn't really get enough credit.
There is:
A) Piracy as defined, where you effectively 'steal' a copy of a game for you to play without paying for it. This is the kind that developers hate, gamers hate, I hate.
B) Piracy as a gift. See, I've often given my little brother/friends a copy of a new game that I've bought that I absolutely cannot get enough of, by letting them log in as me on steam and play it for a bit. Other times, we share CDs and CD keys. This is the kind of piracy developers need more of, because in 9/10 cases, my little brother/friends went and bought their own Steam version, or plan to when they get more money. It's caused the people around me to become interested in a developer's later work. This is the kind of piracy that people who defend piracy try to advocate.
It's important to note that in this day and age, almost every game either has a demo, a friend who can let you try it, or some gameplay videos or reviews that can give you a good idea of how the game is. "Try before you buy" is not a valid excuse for pirating. "I don't like the DRM" is also not okay. Either you boycott it or you deal with the DRM. If it's something rendering the game unplayable offline or something, a crack is fine so you can play your game that you paid for, but it's not okay to torrent the whole game. Anyhow, I'm going to go play some games on Steam, a service with games so cheap, I've never had to pirate a game.
