Decimation wasn't a crossover. It was several *quite* separate stories that just shared the same brand. Same as "M-Tech" in '99, with Machine Man, Deathlok and Warlock getting their quite separate books all under the same banner.

World War Hulk is a crossover, and so is the upcoming X-crossover in the fall, but note I said *big* crossovers once a decade. These are quite small in comparison to Civil War and don't come anywhere close to 100 tie-ins.
