Hey, I don't think you could make this a top rated game, there is already one much better. However, I do think you could make the player need strategy by not letting him get gold by damaging opponent base.
A bit of advice, even though Ive known this a while I'm just posting it now, only buy cards when you have beaten 3 or 4 levels of the five. The cards are best there.
If you ask me, Micro Machine is best. Just keep upgrading your cars speed until you get it, then by the time you get something better you have maxed out all the good stats. I'm only trading it for the last car.
Will you people quit complaining? If you don't like it you shouldn't try downing it with such ridiculous comments. Slippery surfaces add difficulty, how long are you going to wine about that? It's a good game, much better than shift.
To handle the german keyboard, you need to add options for choosing the keys. Kid1er probably just read the description, not the game, and people rate him up because they are looking at the comments before playing. Helicopters are not to hard, on the contrary, the secondary shooters are overpowered.
