Achievement showcase contain hand selected "non-trivial" effort achievement to get. Ordered from the most non-trivial to lesser one.

Some commentary:
- Invisible Inc - Expert Plus achievements. It's definitely a very significant difficulty modifier, completely transform perfect information game to imperfect one by limiting visible area to what visible to your agent. Certainly non-trivial effort to change my usual Expert playstyle to Expert Plus. Also Contingency extended campaign final level is exceptionally tight, I was on verge of losing when I got that achievement. If I was 1-2 turns late, I'm cooked.
- Against the Storm - Prestige 20 - This game difficulty scaling is quite a mess though. I would say proper experience begin at Prestige 10 (trading mechanics now starting to be useful) and P15+ has similar difficulty scaling to Slay the Spire's Ascension. I could mindlessly play P15 or A15 in both game, but 15+ actually has several significant difficulty boost. One of them is extremely painful RNG cut by reducing available blueprint roll (Slay the Spire's Busted Crown relic). It significantly alter probability distribution way too much for my liking, I only occasionally play at P20, usually just P15.
- Shadow Tactics - Okay speedrun badges certainly quite interesting I would say. Got most of them at Hard difficulty. It's quite interesting the dev decided to add tight speedrun badges; pretty sure timer upper bound are based on dev's best time rounded to nearest 30 seconds. Bit tedious, but I found it pretty fun & challenging. Planning & routing then executing loop is pretty good.
- Slay the Spire - Played too much StS automatically gives you this. I'm suck at A20 & A20H consistency.
- Noita - Uh, I don't know what to say about this one. This game has 2 faces, 1 is your usual linear & "brutal" roguelike and the other one is "secret". Unfortunately I believe the main meat and potato of this the is the latter and not many player able to reach it. This achievement requires very long multi run of marathon to get and experience. Exceptionally fun experience of falling sands game and coding with your wand.
- Sekiro - Mmm, chorework. Well, it should be clear why I hate Sekiro's stealth here. It's totally potato & unfun compared to Invisible Inc or Shadow Tactics. I still wonder why this game has GOTY label when Factorio destroy it outright in term of gameplay.
