Today is Mass Effect Day in Steam's EA Week and so they have slashed the price of the original Mass Effect game to just £3.24, 75% off their usual price and a big saving when compared to the offerings from other retailers, the cheapest coming in at £8.85 from ShopTo, more than double the price of downloading from Steam!
Unfortunately, their "special " £17.99 pricetag for Mass Effect 2 is considerably less special, coming in at a good few pounds more than many of the boxed versions of the game (currently available from both Gameplay and Cool Shop for £14.99). That said, if you are a sucker for extras then you might be interested in their exclusive Digital Deluxe edition of the sequel which is priced at £23.99 and comes with the following bonus items: exclusive armour and two weapons, full length original soundtrack, a digital art book, a comic about Liara's mission to track down Shepard and a documentary video about the making of the game.
Mass Effect has a more heavy rpg feel to it, with less focus on combat and, therefore, a much weaker battle system with guns that feel far less realistic and fights lacking in oomph. Thankfully it's still an excellent game and while others have complained about it, I never minded the combat personally.
While the near-unanimous verdict is that the sequel has improved on the orginal in just about every way, I personally still love the first instalment just as much (even without my beloved Mordin and Thane) and if you haven't tried it out yet, it's an adventure well worth embarking upon.
