I'm assuming that Somnus and Omnis Lacrima are taken from Drammatica and Memoria? Kinda wonder, seeing as those are both arrangement albums, whether the in-game versions of those tracks will be different...hmmm

Everything could change before the final game. Somnus from the first album was a direct rip from the very first trailer for Versus 13. It was changed and extended for the second trailer though, so im assuming this version of Somnus isn't going to be used anymore. Omnis Lacri has been featured extensively in trailers and demo footage though, so barring any more direction shifts for the project that is as final as we can assume for now. Same goes with the TGS14 trailer theme. Thank you for the shares either way, and looking forward to hearing more! (Probably the next big thing will be a demo rip in March?)

thank you so much!
