Always found it weird that Sentinal was even in these games.
It's not even a character. It's just one of many robots for the xmen to beat on.
Guess they have a cool design. But still a weird choice.
Eh, it's not that hard to believe.
For COTA to be the start of what Capcom hoped could be a new fighting game franchise, they wanted to try and cover their bases as much as possible. And how could a Japanese game developer be expected to say "No" to a friggin giant robot? Especially when Marvel just gave them the license, their overall blessing and said "go nuts"?
