Realm Grinder‘s reset mechanic has the important effect of speeding the player back to where s/he left off. In MMO terms, think of this as letting your alt quickly play where you main just was. There are drawbacks, but this seems generally a good thing that could be adopted elsewhere in some form.
For those who have not played this sort of game: after a slow first run while you are learning the game, you reset and advance steadily until you hit a wall in terms of progress, when you run out of new multipliers and abilities; you then reset, which gives you a bigger bonus and pushes the wall further out. Realm Grinder accelerates you towards that wall, which sounds bad to phrase it that way so let’s instead say that it brings you back to your personal late game. You are banking progress and continuing, not starting a long journey over.
This will not be to everyone’s liking because some people really love the early game. Alts! New characters! A simpler game in a purer spirit! Let’s say that incremental games do not have the early game feel that The Shire does. And games recognize that you have played the early game enough, hence boosts to near-max level or GW2’s birthday gifts of scrolls to skip the early game. To the extent that the early game is exactly the same whenever you start over, you want to accelerate/skip it; in a game like Civilization, the early game is often more interesting than a same-ish late game.
In Realm Grinder, this works out very well because you explore the early game diversity pretty completely the first time you play a faction. After that, your new multipliers quickly get you back to where you were. If you are going ten or a thousand times as fast, there is no more early game. You go through it as quickly as you can click. As you accummulate gems, you skip the early game and get back to prestige races in minutes rather than days. As you accummulate reincarnations, you zip back to the Mercenary stage in hours rather than weeks. In the late game, these bonuses just push The Wall out a little further, but they are ridiculously effective in burning through the early game, which you already know, to the late game, which might have something new for you.
If you are a “the real game starts at the level cap” player, really trying something new involves getting back to the level cap.
