Just saw them play in NJ a few months ago and they're still great. Can't say I like the new stuff too much, but luckily they must agree since they mostly played classic stuff.
If you like Metallica but can't play an electric guitar, this is the app you need. With 14 different tracks and 4 difficulty levels it's lots of fun for quite some time. Only downside: fingers like saussages will have trouble operating on the iPhone display on difficulty level 3 and 4. \,,/ \,,/
The most simple games are the best on simple devices, and that's why the stickman fits the iphone so damn well. You need just two buttons to let the stickman jump and then rotate, but it's tough as hell. And endless (i made it to 10'000 points).
And, yes, it's free in most app stores.
A 3rd person shooter that's easily playable for anybody since the controls and the aiming are very easy to handle. Add a specacular scenery, various type of villains and a few heavy guns to that and the carnage/fun is guaranteed. What I didn't like: the final enemy was a walk in the park.
Here's a simple iPhone game for people who are not into gaming but have too much time. Easy to beat if you're not a perfectionist. That explains why it has been the most downloaded handheld game ever.
And the birds are cute. I have no idea how they survive all the havoc.
Probably the most addicting iPhone or iPad game I've ever played since it's really (really) ((really)) tough to beat on all levels - at least if you have a job. Offers lots of levels, different aliens to eliminate and a fair amount of weapons to do so.
If you know any tower defense game, this is the king of them all.
Very challenging for people with a knack for playing pool. Talking about angles of incidence:-) Seriously, the game's very neat and quit a bit of a challenge with endless different levels. You guide different streams through different mazes with devices which deflect these streams in various ways.
