The markets are completely different. FM since the 08 version has been breaking the million sales mark and leads across many different countries in their individual markets (friend is Head of Marketing for Sega - Core games). The game is developed by 30-40 full time staff with hundreds more supporting it on a part-time level. I'm not going to indulge our own sales figures, but needless to say, comparing the size of the operation alone, shows a huge difference between the football management market and cricket management, not only is the demand for cricket management a tiny proportion of the biggest sport in the world, compared to one played at a decent level in about 10 countries.
Heck, I doubt even the best selling cricket sims have ever gotten a third of what FM currently sells, let alone comparing it to football sims.
I will also add, I believe Cricket to be an incredibly complex sport, to get it right in either a sim or management context is not easy, FM is good, but it still has some big flaws, but it has the team and backing of Sega to allow it to progress at a quicker rate.
Financially and market-wise, you just cannot compare them. I don't think anyone is making masses of money out of the genre as there isn't much to be made in it. If you aimed high you could well see what happened/happening with Square Enix and Eidos. Realistic demands are important, I do think that the games have been sub-standard, I can only speak for us at ICC but we're making some big steps forward, developing on new platforms and with a bit more freedom than when the game was owned by Empire and I think we have a good future for making better versions as long as we have realistic targets for short and long term, we'll also admit we've made some errors.
I'm sure Oli will agree with me (if he reads this of course) that cricket management and football management games cannot be compared, likewise the sims of the two different genres.
