Well, I think the only similarity is that they both have to do with Disney. Other than that, no. Kingdom Hearts and Kingdom Keepers are both AMAZING, so that could be one other similarity. Also, just in case you would want to know, Kingdom Keepers 3 was just finished, and rumor has it it will be released late August! So keep your eyes out!
The kingdom keepers 3 is about Wayne going missing, and the kingdom keepers have to search for him. Kind of like The Kingdom Keepers 2. Hope this helped! :)
Kingdom Hearts.
First because it's freaking awesome... and second because their isn't anything not to like about it.
There wont be one There is Kingdom Hearts Birth By Sleep and there is going to be Kingdom Hearts Dream Drop Distance
There is no true kingdom hearts 3 but there are multiple other kingdom hearts titles like Kngdom hearts 365/2
Yes, Kingdom Hearts Final Mix is kind of like a second Kingdom Hearts 2, but there are some differences in the storyline.
Kingdom hearts can be played by girls, if that's your thing. I personally have quite a few friends who are also girls who like Kingdom Hearts and I like it too (I am a girl), so go for it!
yes
well, I don't really get your question, but some fighting games like kingdom hearts are the final fantasy series; some of the characters from different final fantasy series appear in kingdom hearts as well.
As of now, no.

Sora dosent like nobodies hartless rikus darkside and every other boss in kingdom hearts
