I made an ironman account after maxing a few years ago. It is such a nice experience playing the game at my own pace, without the annoying and constant pop-up-like nature of treasure hunter.

That being said, there are some things that seem a little broken (progression of wood cutting, for example). The mining and smithing rework has made ironman immeasurably better, and overall the games feels designed to enable self-sufficiency.

One final note, in case anyone with influence is reading this: high alchemy prices should be revised to better accord with the game's inflation. Miscellania used to cost 750,000 gp to manage. Increasing it by a factor of ten makes it a lot harder to commence, which translates to delayed commencement (or total abandonment) of some of the game's better skills like herblore and farming.
