Unless it is wildly different than the first version I'd vote for 'no'.
I purchased the first thinking it was then end all of games but didn't enjoy it much.
It wasn't long until I deleted it completely (from my phone and iTunes).
I know it charmed some but just wasn't for me.
You may well like it tough.
Can't say that it's worth 10 bucks or not because I haven't played it yet, but I would wait for the price to come down to 5.99 and then pull the trigger.
