I don't really know about big game fishing, but they defenitely have a lot of fish in Mexico:

I guess you could rent a boat such as this (with driver) and not pay too much either:

I went big game fishing one time while we were In Florida. I had a lot of fun. I caught something don't ask me what it was. I was so excited at the time I didn't care what it was.

i think Florida is a good place for big game fishing. but i have also heard about Mexio.
