Step 1. Don't listen to friends, because they're usually wrong.
Step 2. Don't listen to previews, because they're paid to make the game look good.
Step 3. Go to
www.metacritic.com, check the score
Step 4. Check Electronic Gaming Monthly's review
Step 5. Check
www.ign.com review
If all of those are in perfect alignment then I will buy the game.
