Call of Beyond has some nice features, but I wouldn't say its farther along than BITS. Namely:
-> Character Customization is not as simple as people think it is. And its not present in Beyond.
-> All the options in BITS works... can't say the same about Beyond.
-> The Beyond map although cool and all, can't be explored due to quick loss of food/water and time. It gets dark way too soon and you take damage unless standing next to your set down lantern. The BITS map is quite big and has at least 1-2 hours of content, while the Beyond map, is like 5-10 minutes.
-> You have crouching, crawling, swimming, climbing, and jumping.
-> Cumshots are better in BITS. As well as gaping and overall scene quality.
-> The intro sequence actually has an intro movie. True, its the intro for Tomb Raider 2013, but still its impressive to see in a porn project.
-> It has an actual tutorial.
I like Beyond too and look forward to what it has to offer, but, its not farther along than BITS. Also it doesn't have save/load yet either. So... when it does, you might argue that it is farther along.
