I have been a hardcore gamer for over 30 years. I live and breathe gaming.
1. The Binding of Isaac
The original Binding of Isaac game was only on PC and I'm typically a console gamer so never got to play it, but the later iterations of the game Rebirth and Afterbirth were on consoles and honestly one of my favorite games of all time. I've been gaming for 30 years. It's a Rogue-like game that I can best describe as a mix of old school Zelda and Bomberman, and you unlock new power-ups and items as you play through—and the unlockables are practically unlimited.
I have been playing for years now and still haven't unlocked everything, with a good variety of different characters to use, each with their own way of playing through the game and 1000's of items to mix and match no two runs are ever alike, the replayability is endless with this game.
2. Path of Exile
Path of Exile is basically a Diablo clone but one that is done very, very well, with what is, in my opinion, a much more in-depth skill tree system. This is a pretty difficult game and perhaps only for hardcore gamers but it is nonetheless a great game. The skill system is unique, instead of choosing skills as you level up you find or buy skill gems and place them in your armor and weapons, any class can use any skill, it makes for endless build possibilities. It is completely free to play and the microtransactions although helpful are not required to enjoy the game to it's fullest.
3. Rocket League
The best way I can describe Rocket League is to think soccer but with cars, although there are hockey and basketball modes as well as a rumble mode kind of along the lines of Twisted Metal.
I can't explain why, but the feel of the controls in this game reminds me of '90s arcade games in the best possible way. With a good amount of different game modes and ranked modes, there is plenty of variety here to keep you entertained. There is also a battle pass like most games these days where you can earn new skins, bodies and all kinds of other unlockables, If you haven't played it yet I advise you do, it is in my top 5 games of all time, as far as fun goes.
4. Enter the Gungeon
Enter the Gungeon is a twin-stick top-down shooter with Rogue-like elements, it is a lot like The Binding of Isaac, there are countless different weapons to use and every run is different, another rogue-like game that's just different enough to be great
5. Fallout 76
The initial release for Fallout 76 was such a mess that many gamers just stayed clear of it, and for good reason. But since release, Bethesda has fixed a lot of the issues and continue to address new issues on a frequent basis, they have also introduced a Survival mode and a battle royale game mode since release, The game wasn't worth playing when it first came out but there are a ton of reasons to play it now and it finally works as it should have from day one.
