I'm new here but not necessarily to the Jaguar library. I was looking for a thread on underrated/underappreciated Jaguar games and didn't find anything, so I'm sorry if I missed something. I feel like some Jag games don't get the love they deserve and I'm curious to get some other takes on this (either OG or homebrew titles).
Here's my list:
Brutal Sports Football -- I think this and NBA Jam are THE BEST 2 player games on the console and pretty much anytime I dust off my Jaguar I always gravitate towards this game. There's just something about watching old muscle heads with gray hair stabbing lizard men with knives and kicking their heads around the field. I love how Overtime is essentially a literal interpretation of "Sudden Death." I always felt the controls were excellent and I know that while it was originally released on the Amiga, they planned on ports for the SNES and Genesis. I'm sad we never got them, but the great pixel art combined with a cool single player tournament mode and pretty solid play mechanics has kept me coming back to my Jaguar for years.
Doom -- I know Doom on the Jaguar gets some love, but I think it deserves more recognition due to it being the only port of the game coded by ID Software and became the anchor which nearly every other port of the game, including the excellent PSX version, were derived from. You could either spend all your parent's cash on a crazy expensive PC, play a handful of crappy console ports, or play the Jaguar version which still holds up today.
Iron Soldier -- I hate mech games, but I adore Iron Soldier (never played the sequel). The first time I played this game and looked down at a tank shooting me from the ground, I was blown away that I could actually see my giant mech feet stomping the crap out of everything in the environment, including the poor tank! I still think the destruction on larger buildings looks pretty good, and this is still the only time I've ever felt like I was controlling this lumbering mechanical monster with a machine gun (and eventually a friggin' chainsaw).
Rayman -- The original is still my favorite version of the game, and I know it's insanely hard and not perfectly balanced the closer to the end you get, but I still think this Jaguar game is one of the best on the console and pretty much any other retro console for that matter. Debatably the best looking game on the Jaguar, Ubi Soft really showed off how well the system could push a bunch of colorful sprites around the screen. The controls are pretty much perfect and the core gameplay is really fun, it's just the level design ranges from excellent to "huh?" after the first couple of stages.
Power Drive Rally -- Another great looking Jaguar game, my only complaint with PDR is that the controls feel a bit stiff. Once you learn how the cars handle though, this is probably my favorite overhead racer in existence. There were some great ones for the Neo Geo, but I felt that you need ludicrous reaction time in those to survive, and I think that PDR found the perfect balance of warning signals and track design. This is another must have for me, even though I know it doesn't push the Jaguar very much, it just has a certain charm to it that you don't get in a lot of games today.
