What do you guys think about experience point rewards in strategy RPGs like Shining Force and Fire Emblem? Most games award EXP to the actor, with bonus EXP when the actor destroys its target. I like this but it does have the problem of "winner keeps winning" such that strong offensive characters snowball ahead. Awarding an even split to the entire party keeps things in balance but also takes EXP control away from the player. Any good alternatives? Otherwise I'm leaning towards the latter.
I'd say some Fire Emblems have found an interesting counterbalance to that with their manual bonus XP system (namely, in Path of Radiance/Radiant Dawn)
The idea is that you're awarded some spendable bonus points (you could either give them to the player via completing secondary objectives, or it's a fixed percentage of all xp gain, or static item drops you need to redeem, or whatever else), which you can then spend on the units of your choice to get them caught up to speed with the others. Gives an incentive to complete some side stuff if the bonus xp is awarded there, and allows you to customize your characters a bit since you can spoon feed your favorites, or spread evenly among everyone, etc.
Invisible Inc. has some of that same logic, where you can only upgrade your agents in between missions using the cash you get during missions, so you're encouraged to explore fully each layout to get more cash to spend on more upgrades. Replace cash with bonus xp, and you're set :-D
