1. geoDefense – A great tower defense game.
2. Sol Free – I think every iPod needs a solitaire game.
3. TapDefense – The first tower defense game I played on the iPod. Its had lots of great updates over the past year.
4. I Dig It – A great little game where you use a digger to dig up items for upgrades and to complete quests.
5. Kingdoms Live (my code is 1SNT3) – An online MMO game that is very addictive!
These would have to be my top 5 games that have withstood the test of time. I just downloaded Zenonia Lite (old school RPG) and am enjoying it a lot. There are a lots of great games out there it just depends on what style of game you enjoy playing. Try out mine and suggest some of yous own!
