I would have loved to have seen this happen.
Not to get too far into comparing the two, but I think that Euphoria in BackBreaker had a ton of more potential than the Infinity Engine. And before anyone gives me the obligatory post about how buggy BB was, I agree, it was. IE was buggy too though. The difference is that everyone, for some reason, is OK with giving Tiburon as much time as they need to get IE perfected, but Natural Motion had to get it right the very first time and they didn't even have any kind of budget.
I can only imagine the kind of Football game that could have been produced from all that potential of Euphoria, if it were handled by a team that actually knew the first thing about American Football.
