If there are to be any future games, I'd love to see Enter the Dragonfly see its full potential. The developers seemingly knew what they were doing but due to the time constraints and lack of game development experience, it was no wonder the game died on its backside and their reputation thrown to the hounds. Toys for Bob have done an outstanding job with the Reignited Trilogy, and I'd trust them to do any of the other games going forward just as well. However, ETD's reputation might set them back.
I wasn't a fan of the TLoS series but I'd give it a go if TfB or VV were behind it, but I'm not sure if we'll see that so soon. Wasn't a lot of the mainstream or marketing appeal generated by big-name actors doing the voices of the characters? Would it do as well without those names? Even then I still think that franchise, indeed Spyro needs to cool down. Alas, with CTR: Nitro-Fuelled being announced, it seems Activision has the momentum to run both franchises into the ground. Let's hope they learn some restraint, eh?
I'm also hoping that since CTR is being rebooted that EtD will get a redeeming little remaster too, but I hadn't quite thought about either series being milked (which is odd since (a) my first instinct is to assume anything popular will follow that route, and (b) it is Activision after all.)
I personally loved TLoS at the time it came out (admittedly I was 10), but I've often pondered on its lost potential since that trilogy was under a lot of pressure to have a game released each year. I wouldn't mind a remaster if it essentially recreated that universe in a way that brought it actual depth and if it brought better storytelling with it, but I don't see that happening.
