What were some games that flew under the radar that had ideas/features that were way before their time?

In your gaming careers what were some games that were overlooked, or perhaps well-known but had a feature or game system that was overlooked that was way before it's time?I feel like in the Original Xbox era there were a lot of games being developed for relatively cheaply that were trying a lot of things that you might never see in a game today. The first that comes to mind was a Majesco release that had an announced, then promptly cancelled sequel on the Xbox One called "Phantom Dust". It was a hybrid action//card game that had a neat online lobby and 'credit' system that allowed you to spend points earned in online matches on new 'packs' of ability cards to refine your character (this was before the era of (micro transactions so there weren't any pay to play systems in the game).The second was a larger, higher profile release called Mech-assault: 2; It sort of fell under the radar because the actual game-play was slower and less fluid than it's predecessor, however the feature it had that blew middle school me away, were it's dynamic, social multiplayer lobbies where you could run around as your avatar (this was mind-blowing back in the day), and its multiplayer component known as "Conquest" which amounted to a map featuring nodes owned by your clan and others online, and as you decided to 'invade' another clan's node you would be presented with a game featuring conditions (game type, map, ect.) specific to that node and had to win in order to 'conquer' that node. It was mind-blowing to twelve year old me to be able to play a game on consoles, online, that had so many mmo-esque features.What were some features in games that didn't quite hit the mainstream that impressed you for the time? via /r/Games https://ift.tt/2WZF1CN
