Steam is not safe from securom and other thoughts
First off, it's not either SecuROM or Steam. Some titles have SecuROM AND Steam. In other words you get a double dose of DRM.
Secondly, the European prices on Steam are so out of whack with reality it isn't even funny. Virtually every single new release can be had for substantially less from any online or bricks and mortar store. To highlight this, Left 4 Dead is €44.99 on Steam and €37.99 on Play.com, postage included. Valves OWN GAME is €7 less from a store! I bought Fallout 3 in GAME for €25 when its €49.99 on Steam. These are just a few examples, and the pattern is virtually the same for other recent titles, including the recently added EA ones.
Steam is a handy service and very slick but its current prices are a scam. It has no cost associated with physically publishing, shipping or stocking titles. Or handling returns. Or stocking hundreds of stores and paying for staff and wages. Yes digital distribution has overheads, for bandwidth, service, support etc. but they are small by comparison. The prices should be MUCH cheaper than they are now to reflect the shorter supply line, reduced piracy and of removal of basic rights such as second hand sales.
At the moment the prices can be fairly described as taking the piss. Buyer beware and shop around. You will save money at the moment.
