I love the trails series, and would be really happy! But I have doubts it will ever go on sale in a bundle like you are asking. Plus, considering the length of the games and good quality of the series, it's fine to buy them for their normal prices anyway.

The Ys already are pretty affordable during sales, at least they do better than the Legend of Heroes series. And while I wouldn't mind them doing a bit better with discounts, their games easily deserve all the support.

And I might be pissed if they'd bundle them after I completed both series. :p

I only played 1 YS game but it was very good, would like to see more.
Also most of them are a bit old so a bundle would be good also for publishers

I think we should get away from the mindset that each and everything should be (or would be nice to be seen) in a bundle. Sure, for some it would be nice. But let's be real, for most people bundles are just a way of hoarding games they never really play anyway.

They also warp our feelings of what games are and should be worth. A few euros for mutliple excellent games is nice for customers but nowhere near a justified for the development costs of these games and often also the quality they provide.

Yeah, it's a shame. They could've at least done one for the 2.5D games or bundle the party system games. But nada. I had to buy every title seperately over the years. The only one I'm missing now is Ys IX (and soon X lol)
