On Thursday this week Sonic will be 19 years old, therefore Microsoft have decided to celebrate by discounting all four of their Sonic titles which are available from the Xbox Live Marketplace.
The four games are Sonic the Hedgehog (the original), Sonic the Hedgehog 2, Sonic the Hedgehog 3 and Sonic & Knuckles, usually these titles would set you back 400 Microsoft points ($5) each, however on the 24th of June they will cost just 240 Microsoft Points ($3) each.
I have already purchased a couple of the Sonic games for my missus, however I may buy the other two for her as an early birthday present while they are cheap!
If you would like to take advantage of these deals check out the following links on Thursday (make sure they are 240 MSP) before you add them to your download queue. Add Sonic The Hedgehog here, Sonic The Hedgehog 2 here, Sonic The HedgeHog 3 here and Sonic and Knuckles here.
