Behind the development of flash games lies an even bigger business. It’s important to observe the current trends for the industry you are working in, especially before deciding what category your next game will reside in.
For example, type “flash games” into Google, and the suggestions algorithm auto-completes your search with “flash games zombies.”
Even simply typing zombie into Google will get you:
This is certainly a reflection of what’s currently being search by the majority.
Zombies are hotter than ever right now (as well as any doomsday type scenario game, not sure if it is in correlation with how the economy is going), and it’s best to take advantage of what most gamers are playing before the market becomes saturated and all the mechanics for that genre type has been used.
The reason being, is not only do you want to get the most exposure for your game, but it also helps expose your brand. Sponsors see this, and if you hit front page, get millions of plays, or win trophies and contests, they’ll definitely be paying attention. A solid brand only solidifies that future games you churn out will be fun to the players, and worth big bucks to the higher ups. A good example of over saturation are Tower Defense games. They were addictive when they first came out, but from what I observe nowadays, most players tend to avoid games with the word Defense in them (myself included). However there are a few exceptions, Plants Vs. Zombies being one of them (but it also has zombies in it!).
I’ve always wanted to make a zombie survival game with mechanics that I personally find fun and fulfilling, and with Project Zombie Ops in the labs, the opportunity couldn’t have been more perfect. So for maximum exposure for your game and brand, research what gamers are currently playing / demanding, and capitalize on them!
