There is not a limit of 20 questions in this version! All you have to do is tag a user and ask a question. Let's get to know each other a little better. @Voxel Studios PSVita or 3DS. There is a example. Have fun guys!
If you're talking about dicks, then none of the above.
If, however, you're talking about 3DS sizes, then I'd have to go with XL because I thought I'd make use of the replaceable cover plates, but I never got round to buying any, which tought me to buy a N3DS XL in the future!
