Battlefield markers: I like the idea - it's like 'making your own history
! In terms of game mechanics, this is like unit statistics for me - like having a page for each unit with total damage, battles fought, %damage done for your side, strongest enemy defeated, etc. Testaments to your exploits.
My main emphasis is on adding another dimension to the map - Lore. Dragon Age uses the Codex to flesh out the religions (Chantry, Old Gods), the various surrounding realms (Orlais, Antiva), heroes of the past (Andraste, Auraline), the place dragons have in the land (are the senient?, hint about dragon cults).
On the surface, marking a Lake and having a bit of text about it seems like so much eye candy. But planned out, it could be used to knit the fabric of the land together with the RIGHT text.
Scorpiana, can you elaborate what you mean by an 'achievement system'? I think I only have a rudimentery understanding about it - it's like collecting?
My main goal was to offer up ways to interact with the Lore. In Dragon Age, you can read a little lore about a past king and how a love triangle brought the land to the brink of civil war and how he disappeared to try and avert war. I'm not finished with the game yet, but it brings to mind - where did he go? Is he still alive? What happened to that great suit of armor that was made for him??
The example of 'the five armorers' was another way to interact with the lore - instead of entering a land that 'was once part of the ancient realm of Felspar, reknown for its mineral wealth and ability to craft fine armor' and that's that - you're able to seek out the five retired great masters of the land for some benefit. Just an example though. To me, it's like building in latent quests into the map.
