That moment when a game comes out of nowhere and ends up claiming your very soul.
I watched Scott Manley's video of the newly released BattleTech (based on the tabletop wargame of yore that I didn't know a whole lot about). I pretty much immediately went and dropped some money on the game because I was pretty much instantly sold.
I have been unable to get off it for the last three days. It's got that 'one more turn' draw like other classic turn based games and more than evokes another game in a similar vein, the Front Mission series. There's something so satisfying about watching 100 ton walking machines of metal lumbering about the battlefield and unleashing destruction upon each other and it feels beyond awesome when you manage to score that lucky hit which removes the annoying weapon from another mech that's been giving your squad a pasting all battle long.
It's a tricky game in spots (you can only field 4 Mechs and you'll often be outnumbered, not to mention trying to keep your merc company from going in the red outside of battle) but it has something many modern games seem to lack these days; a soul. I can't stop coming back to this contest of mechanical wills....and that's a good sign.
