Neopets vs Sinespace
Neopets
Neopets is rather old yet entertaining simulation/virtual world game that lets you adopt and take care of magical and unique pets. This means that you'll be expected to build them a home, buy them food, clothes and other cool stuff. Set in a cartoonish and immense world, you can even set off on exciting adventures with your pet. Best part is that thepets in this game can grow alongside you and they have different looks for different stages of growth, much like the Pokemon in a Pokemon game. There are plenty of fun mini-games to keep you engaged for hours on end as well.
Although the game is a bit on the old side (being released in 1997 and all), the game still holds its charm for players who want a game that's a combination of a usual pet simulation/collection game with a virtual world game. It's free to play and you can play it directly from your browser!
Sinespace
Sinespace is a pretty remarkable, brand-new virtual world game where you can literally be anyone you like, create anything you like, and explore anywhere you like! Setting itself as a direct competitor of Second Life, this game has so much more to offer and it is creator-friendly way too. Not only it is free, creators will almost have unlimited resources to do so and on a platform (Unity3D) that’s as good as it gets. Granted that you’ll probably need to spend hours poring over the game’s documentation and tutorial videos on YouTube to creating something, all the effort you put in will be very well worth it. There are already a couple of creators on board and they have been busy making some items for players to use.Of course, like most virtual world games, there are many worlds for you to explore as well. You can even create your own world and customize it to your liking... or you can simply use one of the several pre-build homes available.
All in all, Sinespace is definitely a strong competitor to Second Life and IMVU especially once it’s fully fleshed out and launched. If you’re interested to get a head start, you can download the game now and start creating!
