User blog comment:Mystic Monkey/What makes a Sonic Adventure game/@comment-24014422-20170626160344

I find both SA1 &2 both adventurous in a sense that they displayed an action-oriented story and a wide gameplay (If there is no hub in SA2, it makes up for it with three stories from the perspective of the playable characters).

I don't remember how many times I replayed SA1, maybe six times or seven. But, what I mostly enjoyed are the long and well-designed stages, and stories filled in mystery that hooked me to replay it and even SA2. Sonic 06 pulled it right with Shadow and Silver's story, in which it showed a true feeling of what determines both characters' actions (Whereas Sonic was not Sonic in that game). But, it could have taken a more refined story and a better gameplay (especially Shadow's speed and him and Silver's upgrades).

You seem to have forgotten Upgrades, which is also an element that distinguishes the Adventure series.
