I know that Civ is a TBS, as is Risk and others, but they tend to get lumped in the RTS genre, especially with mainstreamers that don't know or care about the difference (and that's where the money comes from).
There's still been a lot of mishaps in the genre, mostly because it tends to need to be very meticulously done, with the number of factors involved rising exponentially within the games themselves, and a great deal more emphasis on street dates and sales goals instead of balance and bugfixes. Going to war with the games we have instead of the games we want, if you will. Its resulting in released games that have more patches than most Boy Scout troops, in a genre where the fanbase tends toward patient perfectionism in one form or another.
The 'war' with mobile games isn't won or lost, but is ongoing and will be a factor for the foreseeable future. On a related note, are there even decent mobile RTS games out there?
