Loved AoE II. I still play it on occasion, and I grew up playing it with cheat codes (there’s some silly ones). I think it still holds up well to this day, even with my nostalgia glasses off.

If you’ve never played it, my only caveat would be to expect the AI to not compare to modern iterations. “Balance” in campaign missions sometimes comes in the form of giving the AI an unfair advantage, but everything can be overcome, and you can always save-scum your way to victory. It’s fun, and I definitely recommend a play if you are into retro gaming or RTS’s.
