After buying WWE 12 last year and being really disappointed, I decided to rent WWE 13 so I didn't risk wasting another 40 quid...
After playing it for about 6 days, I still can't decide whether to buy it or not.
There are a lot of good features in the game, but there are also a few bad ones.
There is a slight improvement in the graphics. Some wrestlers look better than others but overall, it's visually pleasing. The menu is simple and the roster page looks good. Although I still don't like that the downloaded wrestlers and divas have their own section. I think it would be much better if they were all on just one roster page.
The new predatory technology is a great new edition. It gives the game a less robotic feel to it, which makes the matches much more enjoyable. Though there are a few glitches where Tables, Ladders etc can just disappear from the ring!
I grew up in the Attitude Era so for me, this is much welcomed inclusion! All the old school wrestlers are there and the commentary is much more relative and less repetitive compared to when playing normal mode. Definitely the best part of the game.
I'm still not a fan of Universe Mode. It gets quite, rather quickly. I still think they should bring back GM Mode from a few years ago. I personally, really enjoyed that feature and thought they could've made it even better! Ah well!
Overall, this is probably the best wrestling game to date. It has a huge roster, the graphics are great and there is pretty much every match to compete it, with every possible title at stake. However, if you're into create mode, playing online and universe mode, you might not be as satisfied as you have been with previous titles.
My advice, rent this game first before deciding.
