Here is few things to remember when you vote:
1. Main reason of the game is advertising ReactOS
2. It should give positive picture about ReactOS
3. The game project is separate project and it should not take time from main developers of ReactOS
4. Runs in Windows and ReactOS (maybe also in Linux but not priority I think)
5. This game is not necessarily included in ReactOS (see 1. )
6. It should be short project (hopefully less than year)

Here is some ideas of the games (from wiki):
* Ballgame by RomanH
o http://www.romanhoegg.ch/Ballgame_Beta.zip
o It should include ReactOS logo or Reacty somehow (Sami)
o still needs a lot of work
(RomanH)o Maybe the balls could be atoms in different colors (Harteex)
* ReactRacer (TuxRacer with ReactOS art)
o Replace Tux with Reacty
* ReactBubble (Frozen Bubble with ReactOS art)
* Super Reacty. A simple side-scrolling jump'n'run game (with ReactOS art)
o Platform: SuperTux (http://supertux.berlios.de/)
o something like Super Mario, Giana Sisters, etc. (RomanH)
o could include Reacty as the main character (RomanH)
o enemies could be pieces of bloatware and malware (gracefully depicted and drawn, of course) (AcetoliNe)
o enemies could also be bugs in the system, which you have to destroy (AcetoliNe)
o The story
+ Reacty is lost into OS-land and finding his way to the net. Reacty is small and not really noticed but the larger OSs, His Mission is to find the coders that will set the world free, He must find the the core coders on the way and the coders will help him to grow bigger,(version number goes up after Reacty vists coders, coders to have familar names and tasks) and pass through different kind of hitches (other operating systems have set up barriers and blocks ower the way). Once reacty has visted all the coders he will be able to pass though the gateway and onto the net.There is also lot of evil bugs, malware and bloatware that is trying to kill Reacty. In the end Reacty will find his way into safe and familiar ReactOS -operating system and he can make ReactOS even better and more compatibility by using all the information gathered in his trip. (Sami, remixed by Headstrong)
o ReactOS logo and webaddress should be included into the the end demo.
o Reacty has many tools to aid him on his trip:
+ Patch shooter: A device that emits patches and bugfixes, the patch shooter can be used to destroy bugs and patch security holes in the system. (AcetoliNe)
+ Antivirus pill: After consuming this pill, Reacty can successfully avoid infection with malware for a limited time (until the virus definitions expire
. (AcetoliNe) * Paintball
o A FPS shooting game using either the Crystal Space or Cube engine
o Cube engine is free/opensource and has bot AI code already
o See engine list below (http://wouter.fov120.com/cube/)
* ReactFighter
o A fighting game between different OS mascots (Harteex)
I think not
