The good & successful game:
Canyon Defense
http://www.miniclip.com/games/canyon-defense/en/
It's highly addictive, excellent realtime strategy game. You have to build turrets to destroy enemy waves of attacking vehicles and jets. There are many types of turrets, upgrades and other buildings.Your opponents vary quite a bit - some can fly, some are fast, some have shields, etc. You can try new approaches and combinations of turret types and placements, so there is also a big replayability factor. Also, there are three maps to play on, and each map needs a very different strategy, so it's quite a challenge.
- there are interesting combinations of turret combinations and their effects -> the game always keeps you interested if there is some better solution
- you are facing various enemy types, your base has to be prepared for various kinds of threats, this keeps the game fresh and changing
- there are 3 maps to conquer with different canyon shape which requires very different strategy approach, you really have to re-think your whole strategy
- good and simple audio/video - you always know what's going on, and it looks good
This game is so addictive, because:
- you have to think both in strategy and in tactic level of playing (you should know what do you want to build in long run, and adapt your plan for next few seconds as well)
- there are different approaches to dealing with enemy and you can even combine these approaches (there is always something you want to try next time)
- the game gets harder, but you get rewards for good playing and you are able to build more, upgrade and build new kinds buildings with new effects on the game (so you have more options)
The bad game:
Alien Attack
http://www.miniclip.com/games/alien-attack/en/
It's an arcade shooting game, where you have to shoot the alien jets appearing on the screen. There is only one type of enemy ships (that you should destroy) and one type of friendly ships (that you shouldn't). The game becomes boring almost instantly. After 5 seconds of playing, you've seen everything and even those 5 seconds are not enjoyable. There is no real challenge, no real fun and there are lots of similar but better games.
