Games that immediately come to mind:
- DISHONORED 2 (!), spectacular level and world design, tons of freedom and possibilities, one of my favs this gen
- Titanfall 2, also really good level design and an entertaining campaign overall
- Sniper Elite 4, caught me completely by surprise and felt almost like a light but gory version of MGS V
- Valkyria Chronicles 4, just as good as the first one with some great QOL improvements
- Metro Exodus, loved the openness and exploration in this, superb atmosphere, great visuals...
- Subnautica, not the biggest fan of survival games (luckily you can disable most of it), but the nail-biting deep sea exploration and dense atmosphere made me fall in love with it
- The Evil Within 2, couldn't get into TEW1, but this one really hooked me and felt more to the point
- Huntdown, amazing pixel art, soundtrack and boss fights, tons of throwbacks to 80s action flicks, just a blast to play from start to finish
Astro Bot is certainly one of the best games of this gen and deserves more recognition, but there's also a barrier to entry, so I can hardly hold someone at fault for missing out on it.
