First, an explanation. Ignore this part if you already know what login events are.
Login Events give Players an practical reason to log in by giving them practical ingame items, like potions. They are made in the shape of “login for an hour today to get x” or “kill 200 monsters your level to get x”. The item in question either depends on the day you log in, or in form of an stamp card, the more days to login, the better the items are that you will get. The company does that to increase player numbers, either direct or indirect.
Second, my suggestions. “You” being IMC.
The most important first: You won’t need login events - to increase the player base - if your game is well made in the first place. You should only make login events to spice the game up. Furthermore, login events only cause players to make multiple accounts to hoard items (i call it account muling), destroying the economy and giving power to the players who don’t play your game.
However, in case login events are unavoidable (or you send out the items by IP, countering account muling), i would highly recommend not having “login for one hour”, since that will only make the players sit around like wet tissues. At the very least let them hunt monsters ( their level range! ). BUT: Don’t let them finish faster by them joining a party! It needs to count their hunted monsters, not the ones hunted by others! What would happen is that crafty players would create partys made out of as many mules as they can fit in, and then kill enemys with a single character, thus causing more hoarding.
As an further recommendation, i suggest shaking up the objectives. Instead of hunting a hundred monsters, the player hunts ten field bosses. Or they craft three items. As for the rewards, be sure you give out items that the players can actually use in their level range, or instead of items, give them exp, money, or drop multipliers ! No, i don’t mean in item form. What i mean is that whenever they hunt monsters, or field bosses, or craft items, they get more exp/money/drops for killing the monsters, or in case of the crafting, they get back some of the materials used.
That’s it, i can’t think of anything usefull to add for now.
