Most of the old parkour maps arent nearly as beginner friendly, or, in my opinion, as fun as newer maps. This is thanks to the higher and higher expectations for build and parkour quality over the years. Sorting maps by newest as the default setting will give new players a more enjoyable experience, because of the better quality of parkour with interesting jumps, great build quality, and more forgiving checkpoint placement. It will also show that expectations for upcoming maps are high, which gives new mappers clearer examples of what an acceptable map should look and play like.
