How would you say I will always like that? My guess is

Ba mhaith liom é sin go brách

How close am I?

I think it's supposed to be Is maith and not Ba mhaith. Ba mhaith translates to "I would like" there.

Would this work ?

Taitneoidh sin liom i gcónaí.

Or: beidh dúil agam ann sin i gcónaí.

Thanks for your replies, but let me rephrase.
I know that "Ba" is the future conditional form of "Is".
I guess what I'm really asking for is the simple future tense of "Is".

Not "I WOULD like", but "I WILL like".

"Ba" is not the "future conditional" as you said, but the past and the conditional.
Now, "is" is the present and the future.
But in many contexts, since it's not possible to know whether "is" is present or future tense, people rather use periphrasis with the verb "bí" or another verb, whose future form is clear:

taitneo(cha)idh, beidh dúil agam...

Oh ok. So, "Is maith liom é sin", without any further clues, could be "I like that" or "I will like that".
But if I said "Is maith liom é sin GO BRÁCH", would the "go brách" part imply I was using the future tense?
Because otherwise, the sentence would mean "I like that forever" which isn't exactly proper language, at least not in English.

I'd say: Taitneoidh sé liom go deo/ go brách.

I don't think using "maith" with future tense sounds right.
