I just wanted to grab some experts’ opinion on this game. How do I adjust here? Or maybe I should never play here at all.

This place I play at has a 3 dollar rake. Sounds good right? Well, the thing is it’s not 10 percent up to 3. It’s just 3 dollars. Period. On any pot that sees a flop. If the pot is 500 .. the rake is 3 dollars. But here’s the killer... if the pot is only 15 dollars the rake is also 3 dollars. That’s like 20 percent!

Obviously on big pots this is great but on smaller pots it’s pretty bad. My experience over maybe 30-40 hours so far shows players are loose and many pots are over 30 in size so I’m saving money VS a 10% up to whatever game.

Should I even bother with this game? If I do (not many other choices).. how do I adjust my strategy?

Yes def play. It's very beatable.
If there was a rake pre flop it might be a different story, but you can generally just play your normal strategy which should be predicated on generally raising pre flop and having pots post flop that are large enough that the rake is only a small portion.

Never open limp. Always raise first in. Other than that, I wouldn't worry too much about it, unless you see a lot of pots that go raise, 1 call, caller folds to a c-bet HU. If that happens often, you might want to size your opens down a bit. Most LLSNL games though, it's not a super common "problem," as the game plays plenty loose to make this rake deal fine.

What steaks?

Nothing to worry about here mate, I wouldn’t adjust your strat.

A few dollars an hour off your bottom line is negligible compared to the game quality, safety, etc.

It’s 1-2 no limit.

Rib eye.

My 1/3 NL game has a $8 rake + $1 BBJ (although no flop then no rake/drop). At 30 hands / hour, if you conservatively guesstimated that the average rake was $5 per hand, then that means an average of $6 * 30 = $180 is coming off the table / hour (before tips, although that is a fair comparison to your case).

At 30 hands an hour, your table is only take $90 off the table, so about half as much. Assuming our tables play with ~similar sized stacks (our 1/3 NL table often sees lots of $200 stacks which would be equivalent to 100bb stacks at your 1/2 table), your table's rake seems really good. This is even more true if you could assume that most pots reach $30 / $3 @ 10% anyways (which is probably true at a lot of LLSNL games).

I will disagree with G's advice above regarding "never open limp" being a necessity. I agree that playing for huge pots will help outrun the rake, but limp/reraising is also a fine way to build huge pots too (although depends on table raising frequency, for how much $$$, for how many callers, etc.). Although admittedly taking down a bunch of dead money preflop at your table won't be as beneficial as at mine.

Raise bigger pre and play deep! Seems like a great rake structure for live 1/2 NL

Totally agree with the above.

The rake structure is in fact so good that you can afford to play more medium sized pots (~$100) than in a 5% capped at $5 raked game.

If you win 7 and lose 6 $100 pots you've net won $29 in the $3 rake game.
If you win 7 and lose 6 $100 pots you've net won $15 in the $5 rake game.

A lot of pots as you know will be in the $80 to $120 range.

The above shows how difficult it can be to achieve a good win rate in a $5 or higher raked game, which most games are. Your $3 raked game is giving you a real good chance at a decent hourly.
