I didn’t really think so, but to each their own! I like the progression from not being able to afford much, up to maxing out upgrades on each tower.

There’s a speed multiplier to cut back on the waiting around. I mostly leave it around 8x speed so it’s a little faster paced.

I think Anuto TD (a tower defense game) is the best I’ve come across.

I also really like Gauguin (Sudoku-esque) and Lexica (word game) on the more casual side.

Don’t know that it’s on F-Droid, but Lichess is also high quality and open source.

Yep, that’s the right train of thought.

I used to also dislike them, due to their limitations vs cash. But eventually realized that I liked having the excuse to go out of town to a fancy restaurant, or splurge on games I might otherwise decide I don’t need right now.

Strictly speaking, cash is better, yes. But gift cards can influence people to do things that might make them happier than typical rational or habitual decisions.
