Hi,
Ah, the good old ultima5 with huge game world and size of 990kB, unpacked. Anyway, with techologies such as bittorrent, 1GB isn't that horrible. Also most of the current PS size is made by art, which mostly remains unchanged, and doesn't need to be re-downloaded in every new version.
*edit*
What comes to the Two Worlds screenshots... very nice. *looks and becomes inspired* *opens PS* Nope, still not changed. Perhaps it takes a little more than that. The three main differences I see are: grand polygon count, huge textures, extensive use of shaders. Personally I partly agree that we should increase the detail of our art a bit. Maybe get rid of those 256x256 textures and loosen the polycount rules a bit. Computers do get more powerful every passing year, and we can add options to lower gfx details so that older machines can run it too.
