hm... Imo achievements would be a nice way to further "personalize" your character.
I see them being something like a combination between Morrowind's and King's Bounty:L,AP,C 's rpg character's development system. You would have your major trees, in which you invest your leveling up points, and then you would have another set of chained and/or unchained abilities that are unlocked/locked depending on your action.
For example(i hope ppl get it
):
You chose the "Carrier Commander" pathway to develop your Hero.
At this title you get:
-. +20% bonus fleet hangar space
-. +35% squadron speed when docking
-. +20% Op on your admiral carrier
On the gameplay path you have the following "achievement" effects:
a. "Brilliant strategist"-you have been a very careful commander, managing your fleet with surprising efficiency, thus winning 50 battles in which you deployed over 4 squadrons without losing a single squadron:
-. +60% fighter+ bomber rearming/repairing speed
-. +25% squadron speed when docking
-. 70% chance that a pilot would eject and arrive safely back when a single craft is destroyed
b. "Wasp Queen" - you favor exclusively fighters and bombers for combat - you won 60 battles in a row only deploying fighter craft and carriers to destroy enemy ships :
-. +100% missile ammo for fighters/bombers
-. +50% fighter/bomber maneuvering
-. +25% amor/hull increase on fighters/bomb
-. +20% extra hangar space required for squadrons
c. "Omelette General" - a small sacrifice is expected and accepted for a fast victory, heroes will be remembered; you won 15 battles in which you lost over 40% of squadrons , but no bigger ships:
-. + if squadron's health is under 25% and high probability of death the ships turn KAMIKAZE on enemy's ass doing 700 dmg per manned craft. Cannot be shot down by flak fire due to eratic maneuvers.
-. Fighters/bombers have -25% armor and hull
-. fighters/bombers have +55% damage increase
These achievements are mutually exclusive. These numbers aren't something I thought about for a long time, just some aprox guesses.
