Gamasutra wins the award for being the first (that I've seen) to pick awards for their best five iPhone games of the year, and the list is respectable, if a little short for such a huge set of possibility. Unfortunately, they don't win any TUAW points for going with Skee-Ball over our preferred Ramp Champ, but Rolando 2 was a worthy sequel to a worthy game, Edge (now Edgy) and Eliss are both great games (too bad you can't play the former, but the latter was underrated for sure), and Space Invaders Infinity Gene deserves to be on almost any end-of-the-year iPhone game list.
Good picks in there for sure. DigitalTrends also has a long list, though strangely, they tend to stick to big names and brands. There are a few gems in there -- Spider, UniWar, and Vay may be a couple good choices that you haven't heard of yet. And here's another top 10 list with some repeats from the ones above and a few more nice picks. I guess with the end of the year upon us, we'll probably have to choose TUAW's favorites of 2009, too, eh? Stay tuned.
