Recommend me a game with a lot of grinding

Disgaea is the best answer for a reason. But I would also suggest Torchlight II (or another Diablo-like, but that's my favourite. Especially the meaningless grind). I find Heroes of Might and Magic 3 is possibly the most relaxing and satisfying time sink I've ever played, for some reason. Dungeon keeper (original) is pretty nice too (building up massive dungeons and forces over several hours and exploring 100% of the map before killing the enemy).

I'd recommend Disgaea D2. Like every other Disgaea game, it's grind-tastic, and it's also the most forgiving since you can't technically get a game over (in the others, you'd have to actually reload your save if you lost. In this one, you're sent back to the main hub and you don't lose anything).

I think D2 is, mechanically speaking, the strongest game the series has had thus far.

Mainly, it eliminates a lot of the pain points:
1) No longer have to reverse pirate to get statisticians (they just appear regularly).

2) Changing monster strength doesn't require a bill to be passed (which was pointlessly lengthy and annoying).

3) Monster Senates can now be bribed (good for when at the end game you literally have 30 trillion dollars with nothing to spend it on)

4) Monster senates for items isn't a random chance in the item world; you can just call them whenever you want.

It just takes a lot of the boring grinding out and lets you do the grinding that's fun

True. I also like how they got rid of the rarity number so that any legendary will give you the same item bonus. No more resetting to get a 0 rarity one to match the others. There's plenty of other little things like that that they streamlined and I love them for it.

As mentioned before, there is Disgaea. When I want to just relax and forget my troubles through mindless grinding I play Disgaea 4: A promise unforgotten and won't do anything to progress the story, but I will end up going up quite a few levels. Another favourite of mine to grind are the Final fantasy games, especially Final fantasy VIII and Final fantasy IX.

Any free-to-play action-RPG for the iPhone.
A couple of hours of fun and progress, then DAYS worth of grinding just to get that one weapon to beat the next opponent (so long as you don't pay for anything, anyway).

Entrian Odyssey and other similar dungeon crawlers.

IIRC Phantasy Star 1 is grind heavy.

Eve Online mining and ratting especially if you get into a mining corp who do mining ops together and is chatty over teamspeak. I hate other MMOs and most grinding games but grinding in Eve is fricking addictive if you run 2 accounts 1 mine 1 hauls, or 2 mines and a corp mate hauls, (I was lucky that my corp joined MCorp in 0.0 and had access to the very best ratting and mining spot in the North lol, but even Empire mining is fun)

Then you build your own ships and get them blown up and have to do ratting/mining again.

Payday 2 is quite grindy...

And there are usually enough players online to make it interesting...

Grinding to level 100 is pretty long... Then with the latest "infamous" update, you have to grind to level 100 about 6 times...
With further grinding planned for the future...

On the harder difficulties it can be a bit challenging though... But if you're going solo, it's not really recommended to play on the tougher levels anyway...
You don't really have to think much... shoot shit until you win... that's about it..

I was going to say Payday 2 as well. It can be tougher and more stressful on the higher difficulties, but given that you want it to take longer and be simpler, you can stick to the low difficulties and just keep on doing simple stuff. It's the number one bag throwing simulator for a reason.
