Cloning rides not so much issue - but using tech to clone with a bigger IP is. (i.e. Star Tour with Iron Man)
I might be in the minority here- but I actually prefer it. I like that GotG is on the west coast and ToT is on the east. Indy vs dinosaur. Mater vs Alien Spin. If we got tron and they got iron man.
Likewise, I like that if we get a GotG coaster, the west coast has a drop tower.
Different theme/Identical ride system
Identical theme/Different ride system
Those two are always my preference vs a direct clone- even if the ride system or theme isn't as good on one coast as the other (our ToT is better but their Indy is better, etc)
For example- with Uni- If we had to use the same ride systems and IPs- I would have rather had F&F and transformers trade ride systems instead of being (almost) exact clones from the west coast.
