I'm going to wait for some reviews and more gameplay videos nearer to release before I decide whether I'll get it or not. I'm worried it's another game that gets hyped up and ends up being disappointing. Either way I'll almost certainly wait for a price drop unless the game gets incredibly good praise from everyone who buys it.
For all people planning to buy it, please do! It really is a great game. It is a matter of opinion, but mine is that it's great and honestly I don't think you will regret it.
I think if you have read some beta reviews an hand ons, you will realize that it's shaping up to be a great game.
For me, it depends. If the game gets good reviews (user AND critic), if I like the gameplay footage, if I hear that they optimized it well, etc. As others have already said, the beta reviews are looking good, but a beta is a beta, so I'm going to wait this one out.
Opting to buy during a steam sale. I hardly do preorders anymore to be honest, game prices just fall too quickly. Shadow of Mordor is already 33% off two weeks into release despite being a really well received game.
I won't buy it right away, because the price is too high for a game for my taste, but maybe if the review will be reaaally good I consider buying it. It's a great game and I want to play it, but what are they puting there as a price tag is just too much.
