Elbert Perez ist Entwickler des Spiels Scribble Defense für die Xbox. Auf seiner Seite schreibt er über die größten Hürden die er bei der Portierung auf WP7 zu beachten hatte.

• The emulator is not throttled, so if you are developing on a beefy machine then you will completely screw yourself over if you do not test your game on a phone before hand. My development machine is a Quad Core I-7, 4 gigs of ram, and a ATI HD 5730. The game runs like butter on my machine, but when run on the phone, it will choke on higher enemy count.
• The emulator is not enough to get the feel of the game. Holding a phone will be a different experience because for one you are not using the mouse as a touch device, and two the way you play will be different on the phone because you hold it different and have a far smaller screen.
• Touch Screen controls are a whole different paradigm than controllers and keyboard and mouse. Doing gestures like pinch, drag, and flick will not always work for a game because it might not be something the user might think of doing. Consider using buttons, and a lot of reminders to the user that this action is available to them.
• You can get away with more on the smaller screen than on the Xbox. The good thing about the smaller screen is that you can cheat on a lot of particle effects by making them have a lower quality and quantity. Remember, the phone will only have a 1ghz CPU, and a even weaker GPU. If you relied a lot on the GPU on the Xbox, you will want to rely more on the CPU this time around
