Is it wrong?

that decision is on you..

It's not wrong, that's what piracy is for. Testing games before you buy them cause most devs/publishers nowadays refrain from putting out demos in fear that you might refrain from purchase after seeing how unpolished or bad it is. But then again, it's entirely up to you. Trust your judgement, not the hype (if there was any regarding this game lol)

Yes, it is wrong

I don't see anything wrong with it, I do it all the time; it's led to quite a few purchases in past years.

it aint wrong, BUT what is wrong is not buying me a computer

Well, i woulndt say it is wrong. But you can also go to your local electronic store, buy it (maybe not register it, if that is possible) and if you cant play it, give it back and say there ist this and that wrong, it's not playable.

Also you could look at the system requirements. Maybe that would help ;)

Technically, yes it is "wrong", as you're acquiring something that wasn't meant to be acquired. A demo, in this case. But then again, it's sort of their own fault for not providing a demo and expecting people to take a risk when it comes to purchasing their game. Demos for all!

I want to make sure game is playable on a decent amount of details.

If that's your only concern, then I think it's perfectly fine to d/l it and run it for 5 minutes or so.

If you download it and log a couple hours of playtime, then you're being dishonest about your reasons for pirating.

I don't resort to pirate copies of games for any reason. I have enough information about the game from reviews, user experiences, gameplay videos, developer interviews, gameplay demos, to make a decision. In some cases, my decision usually gets made months before the release.

Nothing wrong with it IMO. Nowadays demos, even when they exist, rarely showcase any game adequately, and I feel it's perfectly fine to have a good, hard look at the actual game before I shell out money for it.

Don't run it for 5 minutes to "just make sure it's playable". While you have it there, play a few hours, see if you like it or not. If you do, delete the "free" copy and buy it. If you don't, delete the "free" copy and forget about it.

heh, i guess you just posted here to have others convince you if its right or wrong

I think if you play through a tiny bit then it's all right :) As long as you buy it if you realise that you are enjoying it!
