Will you buy such a game if a character you like is in them? Has a crossover game ever made you interested in another series?
I won't buy a game for a single character, but I think the idea of crossovers is good fun.
I bought Pokemon Conquest purely because it was a Pokemon game. I got attached to the characters and ended up getting into Samurai Warriors big time. That had a fierce snowball effect, and I went from SW to being interested in Dynasty Warriors and then interested in Three Kingdoms lore and then interested in real ancient Chinese history and then becoming interested in ancient real-world history in general. Thanks, Pokemon.
