Talk:Ben 10: Ultimate Crossover (Announcement)/@comment-26198499-20110614135340

I'm happy you chose Simien 10 as the first series, but always there is the problem that Simien 10 and all other series are so far away in timeline. Simien 10 takes place in 2050, 40 years after Ben 10. So, it's either Ben goes to the future, or Simien to the past.
