Hmm, the quote feature isn't working on my mobile, sorry about that. I'll just try to reply in order.
Yeah, it's worth it. It was confirmed that the more you have unlocked, the more you'll start with in XV2. Doesn't mean everything you have will be unlocked, but I imagine it'll be like Budokai 3 with B2 save data. You have some extra skills unlocked, depending on your 'completion' %.
Was also confirmed some of the outfits will carry over. The only one that hasn't been expressly talked about is the 'Z-souls', which are called Super Souls now. But I imagine that DIMPS wouldn't leave them out.
Working fan theory right now is, if having the skills/souls doesn't automatically give you some skills/souls, they will likely give you a zeni boost to afford skills right off the bat. So all that transfers, including the character.
As for my liking Xenoverse a lot, yes and no. It's a fun DBZ game, but has faults see SSJ spam, (which isn't a big deal in high level play, but disappointing to see) or the RNG to get an 'ultimate finish', on top of the RNG for getting the drop.. Ect.
I played in all the tournaments and with the exception of the first 2, I placed top 20. Sure I can at least see top 15 with the balancing that seems to have taken place, in XV2. Wouldn't call it the best DBZ title, as that is totally subjective and there is no real objective way to look at a game, outside of pure technical aspects, such as optimal coding, but I would list it iny top 5.
Lastly, I'd like to not have to play PQs anymore, but want my buddy to have at least something when it launches. But thank you for noting the biblical levels of devotion xD
