Realy cause personally i think any one would hold a grudge if after parting with some company they stole your programming and work, retextured it and made money off of it without giving you so much as a cent or even crediting you for the creation of the product! Then continued on to then remake make the rest of your game series just retexturing... Im sorry I don't care who you are even Buda would hold a grudge We are just lucky bungie never seeks to harm its fan base and still makes games for the xbox for that reason, but i can see why they wont expand to apps on a windows phone
