Totally agree, try Braid, Portal 1 & 2, Limbo, Minecraft, Karoshi, World of Goo.. Outlets like xbox live arcade and ios app store make it easier for indie developers to reach a large audience.
Some people ignore indie games, sadly... But you've just mentioned them, so perhaps this person will take a look at them and see what they've been missing :D Because yes, indie games are awesome.
There has been a huge indie golden age in recent times & I'd argue we never had it as good as now in terms of innovative games.
