It has to be asked: What is Bungie's next project going to be? And when will you be releasing the definitive swallow simulation. It's important. Please be sure to include options to add different weights made out of a variety of materials. Will we be seeing multiple types of swallows? Will the Square-tailed Rough-winged Swallow (Psalidoprocne nitens) be included? How about the Grey-rumped Swallow (Pseudhirundo griseopyga), or the South African Swallow (Petrochelidon spilodera)? And will wind and weather be completely simulated in the courses you design? And formation flying to increase efficiency?
