Games!
For all fans of Abduction: World Attack it was a very close run thing between that and Zombie, Run! for the final place in the list.
Re. the hardware, I used my Hero simply because, well, its my phone and I had it to hand, and because there are a lot of them sloshing about in users hands.
Yes if I had taken screen grabs from a Nexus One or Xperia they would have been larger on the page and more impressive and colourful, but the essential game play would have been the same and that is what I was concerned with.
Please keep in mind those screen grabs are actual game play images taken with the Android SDK and have not been tarted up in any way.
As for the new 3D games from Gameloft I tried the only one available at the time of writing - Asphalt 5 - on a mate's Desire and was less than impressed by it. I also understand that none of the news crop of 3D games from Gameloft will run on Android 1.5 or 1.6.
In 12 months time I would expect this list to look very different as games developers take full advantage of larger, higher resolution screens and Snapdragon chippery but for the time being I stuck with games that are just fun to play even on an old G1.
