it is all fake, so why judge which fake thing someone wants to do.
There are many many games with the marriage feature, so I know it is wanted out there. Some games actually give spells if you are married, like a recall spell, where you can call your location and other such features.
Plus really you could ask what is the point in getting married in real life (exculding taxes). I mean all it is is a peice of paper, how can that change anything. Some people do it cus of the symbol of love that it involves, and for those people getting married in a game could also be a symbol of love or commitment.
And to the best of my knowledge there is currently no system in L2 for marriage.
Actual Marriage in this game is impossible atm, BUT that being said I have attended several VERY beautiful weddings ing-game. With the Formal Wear and a bit of roleplay, its quite beautiful and fun, I assure you!
We went to Anghell Falls, had a Master Of Ceremonies and about 20 people, all throwing random assortments of wedding gifts into the center of an adena heart below the bride/bride.
Rather lovely.
A quest that gives you each rings or some other kind of token would be most excellent and *spells/abilities related to it would just be gravy!
*think higher mp/hp regen when within a certain distance of said loved one, teleport abilities that run on a charge 5/5 per say, then once all 5 have been used you undero a lengthy quest to get them refilled, (this prevents unmentionables abusing them) or perhaps a special pink aura when within a 5 foot range...with a heart shape maybe?
