That sadly Isn't true where I live. For $25 I can even get a physical copy shipped home while the retail price in some stores is as low as $22.Compared to what? I saw Tropico 3 at Target yesterday for $39.95, while I can download it from GG for $29.95. Seems like a deal to me. Granted not all the games get that kind of deal, but download prices are very competitive on GG from what I've seen.
Especially not in regards to other fairly new games. GG is generally same price as physical copies, or even more expensive while you don't really get the same product.
A lot of the costs in physical game distribution is rent and salaries, Hardly needed at all for Digital download.
