Even with nothing major done wrong, it is hard not to recommend games of similar genres unless you are on a budget. If you are however, Hellmut can be a very satisfying bite-sized morsel. If nothing else, it puts your reflexes to the test and offers a genuine challenge.
If the only Disgaea game you can get is Disgaea 1 Complete, you will still enjoy yourself. It provides insane hour per dollar value if it scratches your team-building and strategy itches. You may just have to endure and work around some major issues. To those familiar with later Disgaea games, those older problems may be anything from a minor issue to you, to incredibly frustrating. You may still get some enjoyment nonetheless. While it can be purgatory, it is far from hell.
