how is the writing of Xenogears trash?
Chrono Trigger
Only Viper Manor. The body switch onward, especially Chronopolis, Terra Tower and the ending are recycled things that were cut/only partially developed from the second half of Xenogears. This is especially obvious when you find out the save points are spying on you in Xenogears, then Cross, then Saga as well. Also Queen Zeal and Miang are developments of the same character theme/archetype. Wilhelm is the third version. Obviously we don't need to make the connection between Mayneth and Mary (Animus) and Zanza and Yeshua (Anima). Mayneth wanted to expand beyond their bodies, Zanza to contract them into himself, same purposes the two forces filled in the greater meta-series, which is why Telethia are the more or less the same exact thing as Gnosis and Wels.
