Full game with unlimited play time: 60 USD.
How many of your games are you truly playing regularly 6 months after having bought it?
I'm really failing to see why there is an issue with this?
These countries are (most likely) considered poorer and 60USD is ALOT of money over there (note: i have no evidence to back that up) - this is a way for Blizzard to charge less for their game while still providing the full game for a limited period (though I'd hardly call 6 months limited). It is not compulsory. It is another pricing option. I would expect there to be an "upgrade to full version" option to be available at some point.
Something that were it available here, I would most likely take advantage of myself (for SC2, anyway). I'm not the biggest fan of RTS games but if I could pay a third/half of the full price of the game but have it for say, 6 months as opposed to paying full price and having it permanantly, this will give me adequate "try before you buy" time without me having to pay full price.
When paired with an appropriately priced upgrade option (something I see no mention of at this time) I think that everyone is a winner here. I get to try the game legally in an entirely unrestricted format for less than paying full price, and if I like it such that I will still be playing it 6 months down the line, I can get the "full" version. If not, the gametime runs out and again I don't care.
If, after 6 months, it turns out that I need to pay full price to get the "unlimited" version of the game, then this is a problem, however.
