Normally I'm against preorders, unless there's a VERY compelling one, such as an insane early discount like
this, or if you get something free as well, like when Activision gave preorders of Guitar Hero 5 a FREE copy of the unreleased Guitar Hero Van Halen (Seriously, I probably would not have purchased 5 had it not been for the inclusion of Van Halen.) Bundle Stars is having a very interesting preorder for the new Mortal Kombat X game. It's a bundle that includes MK X, the Goro DLC (that lets you play as Goro) AND a copy of Mortal Kombat Komplete (the last one that was released.) And it's all for $44.99. That's cheaper than MK X by itself, and $15 off would have been a good deal as well. As a comparison, to buy all that stuff on Steam now would cost about $80. The sale expires at 12pm Tomorrow (Friday, April 10.)

Not to be outdone, Steam is also having a sale in anticipation of the new Mortal Kombat X, where you can get Injustice: Gods Among Us and Mortal Kombat Komplete for $5 each. I'll be jumping on the MK for $5. Hell if the story mode can keep me entertained for 6 hours like
Angry Joe claims in his review (where he gave it a 9) then it will have definitely earned it's keep in my book. Also Injustice is very good, assuming you haven't picked it up during it's other numerous sales (and giveaways on consoles.)
