Year on year, Yuke's has consistently found ways to make their WWE games more dense and feature complete, and from the first details we've gotten on WWE 2K15, that trend is going to continue. Let’s take a broad overview of just what you can expect from this year's outing in the squared circle – both on last-gen and current gen – starting with the new story mode, 2K Showcase.

Last year, WWE 2K14 electrified with its sprawling campaign mode, 30 Years of Wrestlemania. 2K15 is looking to tell a more focused, up-close-and-personal story than the broad historic view offered in 2K14. 2K Showcase will be broken up into two episodes, each one focusing in tightly on an epic rivalry from the WWE’s past. Think of them as mini-documentaries of a sort. Could it be Rock vs Austin? Undertaker vs Kane? 2K hasn't spilled the beans just yet, but rest assured we'll be the first to know, and when we do, so will you. If the excellent 30 Years of Wrestlemania was any indication, though, the authenticity of the presentation will make these rivalries a treat to play through.

In addition to reliving these golden WWE memories, you'll finally have a true, discreet career mode for your created wrestlers in MyCareer. This mode has been lifted from NBA 2K14 and adapted to the WWE environment. While I didn't think the mode had the right synergy with the NBA, the WWE seems like a logical place to apply it. Imagine replacing all those cheese-ball, amateur hour characters and cutscenes with authentically voiced and mo-capped WWE Superstars. You get the picture. Exact details of the mode are still forthcoming, but we do know that it will be on the current-gen version only. Sorry, 360/PS3 stalwarts.
