Whilst I've slowly weaned myself off pre-purchasing games, it's still a great way of saving some money without having to wait for a sale later in the year. Green Man Gaming's voucher system means you can save even on titles that are already reduced. Enter GMG25-OGRUH-7SM8H for an extra 25% off upcoming titles, meaning you can get the likes of Total War: Rome II for £28.99/$49.99.
Elsewhere on GMG, there's a big Rockstar promotion going on with some of the standout deals being LA Noire for £4.99/$5.99 and a huge GTA bundle for £8.74/$12.49. Looking elsewhere, the Alan Wake franchise is reduced by 80% on GamerGate, whilst there's a trio of new deals on Steam today. The top-down co-op heist game Monaco is half price at just £5.99/$7.49, the space strategy of Sins of a Solar Empire is 75% off at £7.49/$9.99, and the adventure game Deponia is £3.99/$4.99.
