We could give out little graphics for signatures (maye the "r" favicon) for each achievement per game.
For example Captain Commando could be:
One Achievement Point for the following:
- Beat the game once with each character (meaning you have to beat it 4 times)
Beat the game with 3 credits (continues) or less
- Beat the game with 2 credits or less
- Beating the game with 1 credit
- Beat all the bosses without losing a life during that battle
For longer games we can have achievements based on time:
Get to X part of the game in 1 hour... etc
What do you guys think?
