im going to say something i never thought id say in my life..........i agree with wombat. ultimate spiderman is a good series to do a spiderman reboot off of and yes itd be better if he had webshooters instead of organic webshooters ( considering someone in the series already has those).
part of what makes the ultimate series great is the realistic way they deal with him juggling his life, relatioships and superhero duties and itd be cool to see that series brough to life ( especially with a younger hott aunt may).
and the green goblin in the last series of films was damn cheesy he should have looked more like the classic one not completly but in a slightly altered updated form but the mask needed to the same and move realistically. also you needed to have the goblin weapons ( pumpkin bombs, finger zapers, throwing blades).
if they do well with it they could easily use the new siderman flicks to reboot some of the other series into ultimate forms( ultimate xmen for one) while still keeping the successful franchises like Iron man going .
but you were wrong about spiderman games not needing to be openworld its just how you use the open world environment. you need to have destructible environments as well as a kind of cause and effect system where damamge you do or allow to be done could hurt or help you in later missions. add to that having to divide your time being spiderman/ peter parker and the game could be alot more. like how in some sandbox games you can choose to do a mission or not.
