I understand this. But remember that most of the people who are playing LoL/DOTA are not exactly big TV watchers. People that play CoD? They are much more likely to be TV watchers. They go hand-in-hand.
Anyways, I don't know what sort of game would be good on TV. Fighting games, while they have a clear indication of who is winning, happen WAY TOO GODDAMNED FAST for most people to follow. Commentators honestly have trouble keeping up with the action 90% of the time, and can barely accomplish play-by-play simply because by the time they're halfway through a sentence, 3 more things have happened. Starcraft, League, and DotA are on the exact opposite end of the spectrum. It's hard for a spectator to watch and understand who's winning, and you need extremely strong commentary teams to keep people interested without essentially reacting "YEAH LEAGUE OF LEG-ResidentSleeper"
What's the middle ground? What kind of game can we put on TV that is neither too fast nor too slow, is easy to watch and understand, and can appeal to a lot of people? Let's look at another point, why do you think that we see so many video game advertisements on ESPN? Sports watchers are gamers nowadays, and vice-versa. A lot of those people are CoD players. CoD just so happens to be easy to watch and have an idea of what's going on. It plays at the perfect speed where commentators can both explain what's going on and throw in sufficient color to make it interesting, AND the playerbase is already very established. Movement isn't crazy like quake, tribes, or titanfall, so it's really easy for the lay watcher to see and understand the lanes that a person can be moving through, and they don't have to worry about wallruns and double jumps and shit that they don't understand.
On network TV specifically... Fighting games are not the future. MOBA is not the future. FPS is very questionably the future because "OH MY GOD THERE ARE GUNS AND PEOPLE SHOOTING EACHOTHER, PLS BAN THIS FROM TV NAO"
I think that the demographic is there to watch all of these things on TV both in the US and abroad, but frankly there are too many things that can go wrong and too many people who can voice opposition to it. I still think that Twitch should be the main avenue via which eSports are broadcasted, and it's available free and on-demand to everyone in the world provided they've got some sort of internet connection.
This whole x-games thing is cool, and I'll be watching, but I don't think our future is on network television. I wish everyone would just focus on streaming everything online, it's a more readily available and easy-to-consume format than TV can ever be. TV is a dinosaur anyways, if we want eSports to be the future we have to embrace the future, which is specifically NOT TELEVISION
