I'm asking IF they did what other ways can you implement a companion based. As per the original statement FFXI pretty much covered the basics, there isn't much a wyvern can do. ( choco type as per your suggestion ) as a way to attack/ def/ heal ect. The point being ANY game that has a companion can be limited based on class / type specially if none humanoid. Adding emotions is fun when riding a choco so why not, same as some minions will react differently\ based on expressions.
