Limited Run Games has now (through their on-line forum) declared that all Switch title releases will be sold through the 2-week, pre-order system. This decision was made due to the success of Thimbleweed Park sales, which surpassed 13,000, and the popularity amongst LRG fans with the pre-purchase structure.
Of course, as far as special editions of Switch titles are concerned, those will most likely continue to be sold through the same, hectic 10am and 6pm schedule as PS4, PS Vita, and PSVR games. But, if you’re goal is to own a standard copy of every Switch title LRG releases, rest assured, you should now be able to accomplish that with ease.
