ARCADE game VS REAL TIME STRATEGY

So something has just popped in my head, if i was a game developer which type of game should I be making ? off course i want to have a very successfull game... 

Let's say I only know 2 types of game.. Arcade (tetris, zuma, etc) and RTS (Real Time Strategy) such as Farmville, cityville, etc

So.. which game perform better in the market, so i've done a little research by my self and the result is :

observe the above chart i've searched the MAU (Monthly Active User) of 3 arcade game ZUMA BLITZ, BEJEWELED BLITZ and TETRIS BATTLE and compare them with 2 RTS game : CITYVILLE and FARMVILLE

i also searched for the percentage of DAU/MAU = Daily Active User divided by Monthly Active User - for me this indicate the user loyalty, the higher the DAU/MAU the higher the loyalty, imagine 100% all registered member play the game, this will make the DAU/MAU = 100%

so observe carefully, you can see that the Cityville is having difficulty in acquisition, and farmville is having the life of their time, with such high acquisition, same with Bejeweled and Tetris battle.

now, observe the DAU/MAU chart.. the RTS on average DAU/MAU = 21-27% while Arcade DAU/MAU is 22-36%, so Aracade game is slightly higher..

So far from this very short and shallow data i can say if i'm a game developer I'll develop some simple to understand and fun to play arcade game - since its user loyalty are higher.. but if we are talking monetization i'm not quite sure, unfortunately i was unable to find revenue's data for those 5 games - so i cant say much

But i have a hunch or a very strong busines instinct.. do you guys remember how heavy Farmville and Cityville campaign at facebook ? those 2 game ads kept popping on my right hand side screen, but do you ever saw any tetris battel ads ? i havent seen any tetris battle ads.. yet tetris battle has 7 mio Monthly Active User.. it's a big number.. so tetris must have a very good viral feature.. actually the name tetris battle comes from you can play tetris up to 6 person online and battle your score, i guess this kind of gameplay really boost up their member registration number, so i would presume Tetris battle might have larger revenue margin than Farmville or Cittyville but I do think Cityville and Farmville absolute number is still much bigger than the rest, since they have huge number of subscription. 

In a game as complicated as RTS i would suggest all game developer insert some arcade game in it, in order to entertain those bored and tired RTS user with something light,easy and fun, so a hybrid model game will be nice.. Hey if you are smart enough to develop a RTS game i'm sure it's easy for you to develop an Aracade game :) - that is if you agree with an asian mind like my self .. do all the things you can do as much as you can ;p -
